1990 Jefferson Nickel Errors: Value Guide & Rare Varieties
1990 Jefferson nickel error and variety guide. Values for the 1990-S DDO FS-101 ($50–$900+), Full Steps MS67 condition rarities ($1,260 auction), wrong planchet errors ($1,500+), off-center strikes, and Black Beauty errors. Learn to avoid machine doubling traps.
Most 1990 Jefferson nickels are worth face value (5¢), but specific errors and varieties can reach $900 to over $1,500.
- 💎 1990-S Proof DDO (FS-101): $50–$900+ — check IN GOD WE TRUST and the FS designer initials for rounded doubling
- ⭐ Full Steps MS67 business strike: up to $1,260 — requires 5 unbroken step lines on Monticello's base
- 🔴 Wrong planchet error (copper-colored coin weighing ~2.5g): $1,500+ — weigh your coin immediately
- ↗️ Off-center strikes: $40–$1,093+ depending on how far off-center and whether the date is visible
⚠️ Machine doubling — a flat, shelf-like shadow on letters or the date — is extremely common on 1990 nickels and adds zero value. Do not confuse it with a genuine doubled die.

Values shown are typical retail estimates as of 2025-01 and reflect circulated to lightly uncirculated grades unless otherwise noted.
High-grade condition rarities (MS67+ Full Steps) can command significantly higher prices at auction — population reports from PCGS and NGC should be consulted for current scarcity data.
Error coin values vary significantly based on grade, eye appeal, percentage off-center, and market demand at time of sale.
Professional authentication and grading by PCGS or NGC is strongly recommended for any coin suspected of being a valuable variety or error.
Machine Doubling (flat, shelf-like displacement) is extremely common on 1990 Jefferson nickels and has NO numismatic value.
Die Deterioration Doubling (fuzzy, swollen letters) is a normal result of die wear and has no value — do not confuse with true Doubled Dies.
Struck Through Grease (missing or weak mintmark) is a minor error worth only $5–$15. There is no known true 'No Mintmark' die error for 1990 nickels.
The U.S. Mint struck more than 1.3 billion Jefferson nickels in 1990 — nearly every one worth exactly five cents today. But a small fraction tells a different story: a proof coin whose die was accidentally doubled during manufacturing, Gem-quality business strikes so perfectly struck they sell for over a thousand dollars, and dramatic wrong-metal mistakes worth $1,500 or more. This guide shows you exactly what to look for and what to ignore. See standard 1990 Jefferson nickel values →
1990 Jefferson Nickel Specifications & Mintage
Start every error hunt by knowing what a normal coin looks like. Any deviation from these numbers is the first clue that you may have something valuable.
| Specification | Detail |
|---|---|
| Composition | 75% Copper, 25% Nickel — solid alloy, no copper core |
| Weight | 5.00 grams (±0.194 g) |
| Diameter | 21.20 mm |
| Thickness | 1.95 mm |
| Edge | Plain (smooth) |
| Mintmark Location | Obverse (front), below date, right of Jefferson's ponytail |
| Reverse Design | RDV-009 — Felix Schlag's Monticello |
Mintmark location on a 1990 Jefferson nickel: below the date on the obverse, to the right of Jefferson's ponytail.
Mintage by Mint
| Mint | Mark | Type | Mintage |
|---|---|---|---|
| Philadelphia | P | Business Strike | 661,636,000 |
| Denver | D | Business Strike | 663,938,503 |
| San Francisco | S | Proof only | 3,299,559 |
ℹ️ Solid Alloy — No Copper Core
Unlike dimes or quarters, the 1990 nickel is a solid 75/25 copper-nickel alloy throughout — there is no layered core. A normal nickel shows no copper-colored edge. If your coin appears copper-red or bronze all over, that is a potential wrong-planchet error worth $1,500+.

1990 Jefferson Nickel Quick Error Checks
Run through these checks in order. Valuable checks use a 10x loupe (a small magnifying glass used by coin collectors); the wrong-planchet check also needs a digital scale. Each takes under two minutes.
Check 1 — 1990-S Proof Doubled Die Obverse (FS-101) [S mint only]
On S-mint proof coins only. Examine the motto IN GOD WE TRUST along the top (11 o'clock to 1 o'clock) and Felix Schlag's designer initials — two small letters "FS" — below Jefferson's bust near 4–5 o'clock.
Distinct, rounded separation in the letter serifs (the tiny decorative strokes at letter tips) of IN GOD WE TRUST. Very strong doubling on the FS initials — two clearly offset sets of initials. This is Class V (Pivoted Hub) doubling, strongest at 3 o'clock and weakest near LIBERTY.
Machine doubling shows a flat, shelf-like step down — not rounded secondary images. Die deterioration produces fuzzy, swollen letters without crisp notching at the serifs.
Check 2 — 1990-P Doubled Die Obverse (DDO-001) [P mint only]
P-mint business strikes. Inspect Jefferson's tie and vest area, the four date digits "1990", the letters of LIBERTY, and IN GOD under 10x magnification.
Medium spread doubling on the tie and vest. Clear notches at the corners of the date digit serifs, LIBERTY letters, and IN GOD — crisp notches, not flat shelves. Confirming marker: check the reverse (back) for a die crack running from the left side of Monticello to the rim through the letter I of UNITED. This reverse crack confirms the specific die pairing.
Machine doubling (flat shelves) or die deterioration (fuzzy ghosting toward the rim). The reverse die crack is a critical confirming marker — without it, carefully verify the die state before attributing.
Check 3 — Full Steps (5FS / 6FS) [P and D mint, uncirculated only]
Reverse (back). The horizontal step lines at the base of Monticello — Jefferson's Virginia plantation home depicted on the coin. Count the lines from top to bottom. You need at least 5 completely unbroken lines for the FS (Full Steps) designation.
At least 5 fully uninterrupted step lines across their entire width, with no breaks from contact marks, planchet flaws, or weak strike. Six Full Steps (6FS) commands the highest premium. The coin must be uncirculated with no wear.
Steps that appear full to the naked eye but have tiny breaks under magnification do not qualify. Late-state die deterioration can create a false appearance of fullness. Circulated coins cannot qualify for this designation.
Check 4 — Wrong Planchet / Off-Metal Error [all mints]
Overall coin color and weight. A normal nickel is silver-grey and weighs 5.00 grams. A nickel struck on a cent planchet (a blank disk meant for a penny) is copper-red and weighs approximately 2.5 grams.
Copper-red or bronze color throughout the coin, weight of approximately 2.5 grams, and a diameter of roughly 19 mm instead of 21.2 mm. The design may appear broadstruck (cut off at the edges) because the smaller cent planchet did not fill the nickel collar.
Environmentally toned or corroded nickels still weigh 5.0 grams. Copper-plated novelty coins or altered coins may look copper but will have the wrong surface texture. Always weigh the coin before getting excited.
Check 5 — Off-Center Strike [all mints]
Overall coin layout. The design should be perfectly centered. If part of the design is missing and replaced by a blank crescent of metal, the coin was struck off-center.
A clean blank crescent on one side. Value increases with the percentage off-center. Whether the full date "1990" is still visible is the most critical value factor — a 50% off-center with a complete date is ideal.
A slight die misalignment (design fully present but slightly off-center) is not the same thing. Post-mint damage from machinery can create bent edges but will not produce the regular blank crescent of a genuine off-center strike.
Check 6 — Improperly Annealed Planchet "Black Beauty" [all mints]
Overall surface color. Look for a deep gunmetal grey, charcoal, or black coloring across the entire coin. Then tilt it under a light source and watch for the shimmer of mint luster beneath the dark surface.
Uniform dark surface with full mint luster visible underneath when tilted. Full strike detail still present. Caused by excess oxygen in the annealing furnace (the oven used to soften metal blanks before striking) oxidizing the copper content of the alloy on the surface.
Environmental damage produces dull, pitted surfaces without any underlying luster. Coins heated with a torch show uneven coloring or bubbled surfaces. This error is commonly faked — professional authentication is strongly recommended.
⚠️ Trap Check — Machine Doubling (Zero Extra Value)
Letters, the date, or the mintmark appear doubled with a flat shadow shifted to one side. The design elements may look slightly thinner or sheared. Extremely common on 1990 nickels due to high-speed press production.
The secondary image sits flat and lower than the main design — like a shelf stepping down toward the field (the flat background of the coin). A genuine doubled die has a rounded secondary image at the same height as the primary, with split serifs and notched letter corners.
⚠️ Trap Check — Struck Through Grease / "Missing Mintmark" (Low Value)
The P or D mintmark appears faint, mushy, or completely absent. Collectors often hope this is a valuable die-omission error like the famous 1990 No-S Lincoln Cent.
There is no known true No-Mintmark die error for 1990 nickels. A missing or weak mintmark on a 1990 nickel is almost always caused by die grease — a mixture of lubricant and metal dust that clogs the mintmark recess in the die. The affected area will appear rough or rippled, not mirror-smooth like a genuinely omitted mintmark.

1990 Jefferson Nickel Valuable Errors & Varieties
1990-S Proof Doubled Die Obverse (FS-101 / DDO-001)
Normal 1990-S proof (left) vs. FS-101 DDO showing split serifs on IN GOD WE TRUST (right).
Origin & Background
Proof coins are struck with polished dies and special care — yet errors in the die-making process can still occur. The 1990-S DDO is the result of Class V (Pivoted Hub) doubling. During die production, the master hub is pressed into a softened steel die multiple times. If the die shifted slightly between impressions — pivoting around a point near 9 o'clock (near LIBERTY) — a second image was engraved overlapping the first. Because of the pivot mechanics, the doubling effect grows stronger as you move away from the pivot point. The strongest doubling falls near 3 o'clock and along the bottom of the design, making IN GOD WE TRUST and the FS initials the prime targets. This variety is cataloged as CONECA 1990-S DDO-001 / UVC-1497 / DMR-002 and listed as a major variety in the Cherrypickers' Guide (FS-101).
The FS designer initials below Jefferson's bust — easiest pickup point for the 1990-S DDO, showing two offset sets of initials.
How to Identify
- IN GOD WE TRUST (11–1 o'clock): Distinct rounded separation in the letter serifs. Look for a notched secondary image — not a flat shelf, but a second raised impression slightly offset.
- Felix Schlag initials (FS, 4–5 o'clock): The easiest pickup point. Under 10x magnification, the two initials should show two clearly offset sets — very strong doubling here due to distance from the pivot.
- LIBERTY (near 9 o'clock): Shows less dramatic doubling because it is closest to the pivot point; minor thickening or notching may still be present.
- Verify die stage: Early Die State (Stage A) shows the sharpest, most distinct doubling.
False Positives to Avoid
Machine doubling — the flat, shelf-like shifting caused when a die bounces during ejection — is frequently mistaken for a genuine DDO on proof coins. Machine doubling reduces the apparent size of design elements (they look shaved or sheared). Die deterioration creates fuzzy, swollen letters without crisp notching. Neither has any numismatic premium. The FS-101 has a crisp, rounded secondary image — never a flat shelf.
Market Values
- Raw (unattributed in proof set): Face set value if seller is unaware
- PR67–PR68 DCAM attributed: $50–$150
- PR69 DCAM attributed: Significant premium over the standard $15–$25 PR69
- PR70 DCAM: ~$900
Auction Record
Approximately $900 for a PR69/PR70 DCAM attributed FS-101 example (recent sales). See the Variety Vista attribution page for full diagnostic details.
1990-P Doubled Die Obverse (DDO-001)
1990-P DDO-001: notching on the 1990 date digits and Jefferson's tie area compared to a normal coin.
Origin & Background
The Philadelphia Mint produced a verified Doubled Die Obverse for 1990, listed in both the Wexler die variety files and on Variety Vista DDO Listings. Less dramatic than the proof DDO, this variety is a legitimate collectible for business-strike variety specialists who search rolls and bags of circulation coins.
How to Identify
- Primary diagnostics: Medium spread doubling on Jefferson's tie and vest area. Clear notches at the corners of the date digits "1990", the letters of LIBERTY, and IN GOD.
- Confirming reverse marker (Stage A — Early-Mid Die State): A die crack running from the left side of Monticello to the rim through the letter I of UNITED on the reverse. This crack on the back of the coin confirms the specific die pairing that produced the DDO on the front.
False Positives to Avoid
Machine doubling is rampant on 1990-P business strikes due to high production speeds. It creates flat shelves — not notches. Die deterioration doubling (DDD) produces a foggy, spread-out ghosting effect toward the rims. Both are worthless. If the reverse die crack is absent, exercise extra caution before attributing as DDO-001.
Market Values
No auction record is established for this variety at the time of writing. Attributed examples command a premium with variety specialists. Consult current Variety Vista listings and recent certified coin auction results for market pricing.
1990 Jefferson Nickel Full Steps (5FS / 6FS)
Five fully unbroken step lines (left, FS) vs. steps with contact marks and weak areas (right, non-FS).
Origin & Background
The "Full Steps" (FS) designation is not a grade but a strike qualifier added by PCGS and NGC to note that the horizontal steps at the base of Monticello on the reverse were fully struck up. The 75% copper, 25% nickel alloy is extremely hard — it resists flowing into the deepest die recesses. Combined with the high-speed press operation of 1990, the Monticello steps were often the first detail to fail. While over 1.3 billion nickels were struck that year, the number certified MS67 FS by PCGS is typically in the low double digits — a survival rate of roughly 0.05% for gem-quality coins.
How to Identify
- Examine the reverse under 10x magnification with strong directional lighting. Tilt the coin to cast shadows into the step recesses.
- Count the step lines from top to bottom. For the 5FS designation, all 5 must be completely uninterrupted across their full width.
- For the 6FS designation — the absolute pinnacle — all 6 lines must be unbroken. This commands the highest premium.
- The coin must be uncirculated (no wear on Jefferson's cheekbone or hair high points).
False Positives to Avoid
Steps that look full to the naked eye often have tiny contact marks or planchet disturbances under magnification that disqualify them. Late-state die deterioration can create an appearance of fullness by softening the step outlines — a paradox that tricks many collectors. Only professionally graded coins with the FS designation on the slab label can be trusted. See PCGS CoinFacts for the 1990-P FS and 1990-D FS population data.
Market Values
- MS65 FS: ~$15–$30
- MS66 FS: $30–$60 (approximate)
- MS67 FS: Condition rarity — see auction results
Auction Record
$1,260 for a PCGS MS67 FS 1990-P nickel (eBay, April 2, 2018 — Top Pop 2 at time of sale). See PCGS Auction Prices for the 1990-D series for comparable data.
1990 Jefferson Nickel Struck on Wrong Planchet (Off-Metal Error)
A nickel design struck on a cent planchet: copper-red color, smaller diameter, broadstruck appearance.
Origin & Background
Coinage presses are fed from large bins of planchets (blank metal disks). If a cent planchet — a disk intended for a Lincoln penny — was left in a tote bin later filled with nickel planchets, it could be fed into the nickel press. The nickel dies would then stamp the Jefferson/Monticello design onto a copper-plated zinc disk meant for a cent.
How to Identify
- Color: Copper-red or bronze throughout (not just toning on the surface).
- Weight: Approximately 2.5 grams instead of the standard 5.00 grams — weigh precisely with a digital scale.
- Diameter: Approximately 19.05 mm instead of 21.2 mm. The cent planchet is smaller than the nickel collar, so the design may appear broadstruck (spreading outward, potentially cutting off edge detail).
- Third-party authentication (PCGS or NGC) is essential before sale.
False Positives to Avoid
Toned, corroded, or environmentally damaged nickels can appear darker or discolored, but they still weigh 5.0 grams. Novelty copper-plated nickels or altered coins may look copper but are not genuine mint errors — the plating is usually visible at the edge. Always weigh first. Do not clean the coin.
Market Values & Auction Record
A comparable 1989-D nickel struck on a cent planchet has realized over $1,610 at auction (Heritage Auctions). A 1990 example with a visible date would command a similar or higher figure depending on eye appeal and strike quality. This error type has a broad collector base — it crosses into type error collecting and is immediately visually dramatic, ensuring strong demand.
1990 Jefferson Nickel Off-Center Strike
A 1990-D nickel off-center strike showing a blank crescent and shifted design with full date still visible.
Origin & Background
An off-center strike occurs when the planchet is not properly centered over the lower die when the upper die descends. Part of the planchet sits outside the die face entirely, leaving that area blank while the design is stamped on the portion that was under the die.
How to Identify
- A blank crescent on one side of the coin with the design shifted toward the opposite side.
- Estimate the percentage off-center (10%, 25%, 50%, etc.).
- Check whether the full date "1990" and mintmark are still visible — a coin with these present is worth significantly more.
- Note the clock position of the shift (e.g., "design shifted toward 12 o'clock").
False Positives to Avoid
A broadstrike — struck outside the collar but still centered — is a different (and generally less valuable) error. Post-mint damage from heavy machinery can create irregular edges or bent rims, but these do not show the characteristic clean blank crescent of a genuine off-center strike. Metal flow on a struck coin differs from damage.
Market Values
- 10–20% off-center: $40–$100
- 50%+ off-center with full date: $200–$1,093+
Auction Record
$1,093 for a 1990-D MS66 off-center strike (Heritage Auctions, December 13, 2004).
1990 Jefferson Nickel Improperly Annealed Planchet ("Black Beauty")
Improperly annealed nickel showing deep black oxidation with cartwheel mint luster visible beneath when tilted.
Origin & Background
Before striking, planchets pass through an annealing furnace — an oven that softens the metal so the dies can fully fill the design recesses without cracking. This heating must occur in an oxygen-depleted atmosphere. If the atmosphere contains too much oxygen or the planchets remain in the furnace too long, the copper content of the 75/25 alloy migrates to the surface and oxidizes, creating a deep, uniform dark coating on the planchet before it is ever struck.
How to Identify
- Uniform deep gunmetal grey, charcoal, or black surface coloring across the entire coin.
- Full mint luster (cartwheel shimmer) visible beneath the dark layer when tilted under directional light — this is the key test.
- Full strike detail retained — the design should be sharp despite the dark surface.
False Positives to Avoid
Environmental damage (dipping in chemicals, soil burial, PVC damage) produces dull, pitted surfaces with no underlying luster. Torch-heated coins show uneven coloring and often bubbled or blistered surfaces. Chemical blackening agents leave an artificial texture. Because fakes of this error are common, PCGS or NGC authentication is strongly recommended before assuming any value.
Market Values
Genuine 1990 examples are rare and highly collectible. Specific 1990 auction data is not established in current records. Comparable improperly annealed nickels from other modern dates with PCGS/NGC certification command significant premiums. Do not attempt to value or sell without professional authentication.
1990 Jefferson Nickel Common Traps & False Alarms
These four patterns fool collectors constantly. None adds meaningful value. Recognizing them saves you from overpaying or getting excited over a common coin.
⚠️ Machine Doubling (MD)
The date, letters of LIBERTY, IN GOD WE TRUST, or the mintmark appear to have a shadow or secondary image shifted to one side. This is by far the most common "doubling" found on 1990 nickels.
During the ejection phase of striking, the die can bounce or drag slightly across the freshly struck coin surface — shearing or pushing the top layer of metal. It is a surface defect on the coin, not an error in the die itself.
- The secondary image is flat — it sits lower than the main design like a shelf stepping down to the coin's field (background).
- The main design element often looks thinner or shaved — metal was pushed away, not added.
- A genuine doubled die has a rounded, raised secondary image at the same height as the primary, with split serifs and notched letter corners.
Value: Face value only (5¢). No exceptions.
Machine doubling (left, flat shelf) vs. genuine doubled die (right, rounded raised secondary image with split serifs).
⚠️ Die Deterioration Doubling (DDD)
Letters, the date, and design elements appear swollen, fuzzy, or have a "ghosting" shadow — often most pronounced near the rim. Can look impressive under a loupe.
As a die wears down from striking millions of coins, metal flow erodes the die face, causing design elements to spread and look bloated. It is a normal result of die age, not a manufacturing error in the die-making process.
- The doubling is fuzzy and spread — not crisp and notched like a true doubled die.
- Most prominent toward the rim; the center of the coin often looks normal.
- No split serifs — the letter tips look bloated, not separated into two distinct images.
Value: Face value only.
⚠️ Struck Through Grease / "Missing Mintmark"
The P or D mintmark appears faint, mushy, or completely smooth — as if it was never there. Collectors hope this is a die-omission error like the famous 1990 No-S Lincoln Cent, which is worth thousands.
A mixture of lubricant and fine metal dust ("grease") fills the mintmark cavity in the die. On the struck coin, the area where the mintmark should appear is flat or slightly rough instead of fully raised.
- There is no known true No-Mintmark die omission for 1990 Jefferson nickels — only the Lincoln Cent had that famous error that year.
- The grease-filled area will appear rough or rippled under magnification, not mirror-smooth like a polished die would leave.
- These minor errors trade for $5–$15, not the thousands commanded by true die-omission errors.
Value: $5–$15.
Grease-filled die mintmark area: rough, rippled surface where the P mintmark should appear — not a valuable error.
⚠️ Post-Mint Damage & Cleaned Coins
Coins that appear discolored, strangely dark, unusually shiny, or with altered surfaces. Sometimes mistaken for a Black Beauty error or a polished proof. Cleaned coins often appear harshly bright with fine hairline scratches under a loupe.
Chemical exposure, abrasive polishing, or mechanical damage after the coin left the Mint. These alterations happen outside the Mint and have nothing to do with manufacturing.
- Cleaning leaves hairline scratches visible under 10x magnification — a natural coin surface shows no such lines.
- Dark environmental toning is patchy and dull, not uniform with underlying luster like a genuine Black Beauty.
- Grading services (PCGS/NGC) will identify cleaned coins and label them accordingly, significantly reducing value.
Value: Face value to minimal premium. Never clean your coin.
1990 Jefferson Nickel Grading & How Grade Affects Value
Coins are graded on the Sheldon scale from 1 (barely identifiable) to 70 (perfect). For 1990 nickels, the value action is almost entirely in the MS65–MS67 range. Here is what each tier means:
- Circulated (VF–AU, grades 20–58): Shows wear on Jefferson's cheekbone, hair, and coat. Worth face value regardless of grade.
- MS60–MS64 (Uncirculated): No wear, but may have bag marks (small scratches from contact with other coins during transport). Nominal premium — $0.25 to low single digits.
- MS65 (Gem Uncirculated): Strong luster with few marks. Value: approximately $15–$25.
- MS66 (Choice Gem): Superior luster with minimal marks. Value: approximately $30–$88.
- MS67+ (Superb Gem): Where values climb sharply. The combination of extreme scarcity and registry set competition drives prices here.
⚠️ The Full Steps Effect
Grade alone does not tell the whole story. A 1990-P MS67 without Full Steps might sell for a modest sum, while the same coin in MS67 with Full Steps sold for $1,260 at auction. The FS designation proves superior die pressure and strike quality — and registry set collectors pay heavily to obtain it.
Only coins graded by PCGS or NGC carry credible grade designations. See NGC Coin Explorer for the 1990-D for population data.
1990 Jefferson Nickel Authentication Guide
Not every 1990 nickel warrants professional grading, but some absolutely do. Here is when to submit to PCGS or NGC — the two most widely respected third-party grading services (TPGs):
- 1990-S Proof DDO (FS-101): Always submit. Attribution as FS-101 on the slab label is required to realize maximum value. An unattributed DDO in a raw proof set is often overlooked.
- Wrong Planchet / Off-Metal: Always submit. These errors are commonly faked; a PCGS or NGC holder provides buyer confidence and dramatically increases sale price.
- Black Beauty (Improperly Annealed): Always submit. Counterfeits are common; authentication is not optional.
- Off-Center Strikes (25%+ off-center): Submit if the error is dramatic and the date is visible. Authentication and grading boost buyer confidence at auction.
- Business strikes in MS67 or higher: Submit if you believe the coin reaches this grade and shows Full Steps. Population is low enough that a top-pop coin in a PCGS/NGC holder commands significant auction premiums.
💡 Strategy Tip
For proof sets, compare the 1990-S nickel to other coins in the set under 10x magnification before deciding to break the set open. If you see the FS-101 doubling, crack it out carefully and submit only the nickel. The remaining proof set still has value.
Dealer referral information: consult the American Numismatic Association (ANA) dealer directory or attend a regional coin show for in-person evaluation of high-value errors.
1990 Jefferson Nickel Frequently Asked Questions
Is the 1990 Jefferson nickel rare?
No — over 1.3 billion were struck for circulation across Philadelphia and Denver. Circulated examples are worth exactly 5 cents. However, specific subsets are genuinely rare: MS67 Full Steps business strikes (only dozens certified), the 1990-S Proof DDO FS-101 (a major variety), and dramatic mint errors like wrong-planchet strikes.
What is the 1990-S DDO and how much is it worth?
The 1990-S Doubled Die Obverse (FS-101) is a proof coin whose die was accidentally impressed twice at slightly different angles during manufacture, leaving a doubled image in the steel. Every coin struck by that die carries the doubling. Look for rounded, notched doubling in IN GOD WE TRUST and the FS designer initials. In PR69–PR70 DCAM grades it has sold for approximately $900. Even raw (ungraded) sets can be worth hunting if you suspect this variety.
How do I check my nickel for Full Steps?
Flip the coin to the reverse and look at the base of Monticello (the building). Under a 10x loupe with strong directional light, count the horizontal step lines from top to bottom. For the 5FS designation you need all 5 lines completely unbroken across their full width. For 6FS, all six must be unbroken. Any contact mark, planchet flaw, or weak area that interrupts a line disqualifies the coin. The coin must also be uncirculated.
My 1990 nickel looks doubled — is it valuable?
Probably not. Machine doubling is rampant on 1990 nickels and is the most common source of false excitement. If the secondary image is flat and sits lower than the main design — like a shelf — it is machine doubling, worth nothing. A genuine doubled die has a rounded, raised secondary image at the same height as the primary, with split serifs (the decorative tips of letters show two distinct branches). If you have rounded, notched doubling on the motto or FS initials of an S-mint proof, you may have the FS-101 — that one is worth pursuing.
My 1990 nickel looks copper-colored — is it valuable?
Possibly. First, weigh it precisely on a digital scale. A normal nickel weighs 5.00 grams. If your coin weighs approximately 2.5 grams and appears copper-red throughout, it may be struck on a cent planchet — a major mint error worth $1,500 or more. If it weighs 5.0 grams, the color is environmental toning or post-mint damage and the coin is worth face value. Do not clean it while you investigate.
Is there a 1990 "No Mintmark" nickel like the famous No-S cent?
No. The famous 1990 No-S error affected the Lincoln Cent only, where the S mintmark was omitted from the proof die by mistake. There is no known equivalent die-omission error for the 1990 Jefferson nickel. A 1990 nickel with a missing or weak mintmark is almost certainly a struck-through-grease error (lubricant clogged the die recess), which is worth only $5–$15 — not thousands.
Should I clean my 1990 nickel before having it graded?
Never clean a coin you intend to submit for grading or sell. Cleaning destroys the original surface and is immediately detectable by grading services under magnification. A cleaned coin will receive a "details" or "improperly cleaned" designation from PCGS or NGC, reducing it to a fraction of its potential value. Handle coins by the edges only.
Where can I sell a valuable 1990 nickel error?
Major auction houses like Heritage Auctions handle high-value numismatic errors and have established records for 1990 nickel errors — a 1990-D off-center strike in MS66 sold there in 2004 for $1,093. For certified varieties and condition rarities, PCGS and NGC registered auctions also attract serious bidders. Always authenticate and grade the coin before selling any error worth over $100.

A note on images: To help illustrate coin diagnostics and rare varieties — especially complex errors that are difficult to describe in text alone — this guide uses AI-generated images. All written values, diagnostics, and variety attributions have been manually reviewed against the cited sources above. While our editorial team works to ensure every image is accurate and helpful, AI-generated illustrations may occasionally misrepresent fine details. If you spot any discrepancy between an image and its written description, please contact us or leave a comment below — we review all feedback and correct errors promptly. Numismatic knowledge is a community effort, and your input helps us build a more accurate resource for everyone.
