1999 Jefferson Nickel Errors: Value Guide & Rare Varieties
1999 Jefferson Nickel error coin values: Bonded Pairs up to $1,750, Wrong Planchet errors $800–$1,500, Off-Center strikes $35–$125+. Spot fakes, avoid traps. Updated January 2026.
Most 1999 Jefferson Nickels are worth face value (5¢), but catastrophic mint mistakes — fused pairs, wrong-metal strikes — can top $1,750 at auction.
- 🏆 Bonded / Mated Pair (two coins fused together): $1,000–$1,750+
- 🏆 Wrong Planchet (nickel design on a dime blank, weighs ~2.27g): $800–$1,500
- ✅ Major Off-Center Strike (>50%, date visible): $35–$125+
- ✅ Double Struck (two overlapping impressions): $50–$200
⚠️ Biggest trap: Dark red, brown, or black 1999 nickels are almost always environmental damage — not rare Improper Annealing. Check for surface pitting under a 10x loupe. Pitting = damage, smooth luster = possible error.

Values shown are typical retail estimates as of 2026-01.
Error coin values vary significantly based on grade, eye appeal, and current market conditions.
Professional authentication (PCGS/NGC) is recommended for any coin suspected of being a major error — submission costs $30–$60+ per coin.
Machine Doubling (flat, shelf-like doubling) is NOT a valuable Doubled Die variety.
Dark-colored 1999 nickels are almost always environmental damage, not Improper Annealing errors. Check for surface pitting under magnification.
Jefferson Nickels are a solid copper-nickel alloy — they do NOT have clad layers. A copper-looking nickel is environmental damage, not a missing clad error.
Data confidence for minor 1999 DDO/DDR varieties is low — no major auction records exist. Treat high-priced variety listings with extreme skepticism unless accompanied by TPG attribution.
More than 2.2 billion 1999 Jefferson Nickels rolled off presses in Philadelphia and Denver — making them some of the most common coins ever minted. Most are worth exactly 5¢. But a tiny fraction escaped as catastrophic disasters: coins fused together in the press, nickel designs stamped onto dime blanks, or strikes so far off-center only a sliver of Jefferson's face survived. Collectors pay hundreds — sometimes over $1,750 — for these flukes. This guide tells you exactly what to look for. See our complete 1999 Jefferson Nickel value guide for standard coin pricing.
1999 Jefferson Nickel Specifications & Mintage
Before hunting errors, know what a normal 1999 nickel looks like. Any deviation from these specs is your first clue that something unusual happened at the Mint.
| Specification | Detail |
|---|---|
| Series | Jefferson Nickel |
| Composition | 75% Copper, 25% Nickel — solid alloy (no clad layers) |
| Weight | 5.00 grams (±0.13g tolerance) |
| Diameter | 21.20 mm |
| Edge | Plain (smooth, no reeding) |
| Magnetic? | No — if a "1999 nickel" sticks to a magnet, it is not genuine |
| Reverse Feature | Monticello; Full Steps (FS) designation awarded to sharply struck examples with all six steps fully defined |
1999 Mintage by Mint
| Mint | Type | Mintage | Circulated Value | Mint State Value |
|---|---|---|---|---|
| Philadelphia (P) | Business Strike | 1,212,000,000 | 5¢ | $0.25–$1.00 (MS63–65) |
| Denver (D) | Business Strike | 1,066,720,000 | 5¢ | $0.25–$1.00 (MS63–65) |
| San Francisco (S) | Proof (Deep Cameo) | 3,347,966 | N/A | $2.00–$8.00 (PR69) |
Standard Value Summary
Circulated 1999-P and 1999-D nickels are worth face value (5¢). Uncirculated (MS63–MS65) examples carry a modest $0.25–$1.00 premium. High-grade MS66–MS67 coins with a Full Steps (FS) designation — meaning the six steps of Monticello are fully defined with no breaks — can reach $500+. For error coin values, see the table below. Full denomination data: 1999 Jefferson Nickel Value Guide →
1999-S Proof Nickel Values
San Francisco struck 3,347,966 Deep Cameo Proofs (DCAM) for annual Proof Sets. These have mirror-like fields and frosted raised devices — they were never released to circulation. A non-Proof coin showing an "S" mintmark is suspicious; verify the mintmark has not been artificially added. Values: PR65–PR67 DCAM: $2.00–$5.00; PR69 DCAM: ~$8.00. PCGS CoinFacts: 1999-S DCAM →
1999 Nickel Quick Checks: Do You Have a Valuable Error?
Run these three checks before anything else. The first two identify coins potentially worth $1,000+. The third prevents a very expensive disappointment. Required tools: a digital scale (accurate to 0.01g) and a 10x loupe (jeweler's magnifier, available for a few dollars).
A genuine 1999 nickel weighs 5.00g. A nickel on a dime planchet weighs ~2.27g — the scale test is definitive.
Check 1: Bonded / Mated Pair (Catastrophic Strike)
The entire coin — its profile, edge, and thickness. These errors are dramatic and obvious. They will not fit in a standard coin roll.
Two or more planchets fused together, or a single coin deformed into a crushed, bottle-cap shape. Look for metal flow lines radiating from the strike point. Mated pairs fit together like puzzle pieces. The Jefferson design may be stretched and ghosted across elongated metal.
Post-Mint Damage (PMD) — coins smashed with a hammer, flattened on railroad tracks, or melted by heat. PMD produces random crushing without the structured metal flow lines and puzzle-piece fit of genuine bonded errors. Do NOT try to separate a fused pair.
Check 2: Wrong Planchet — Nickel Design on a Dime Blank
The coin's diameter, rim, and — most critically — its weight. The coin will look noticeably smaller than a standard nickel, with lettering truncated at the edge ("LIBERT" instead of "LIBERTY").
Weight is the definitive test. A nickel struck on a dime planchet (blank) weighs approximately 2.27 grams, not the standard 5.00 grams. The dime planchet is also smaller: 17.9mm vs. 21.2mm for a standard nickel.
"Dryer coins" (tumbled in a clothes dryer until the rim collapses), acid-etched coins, or filed-down coins. These weigh slightly less than 5.0g but not exactly 2.27g. Also: 1999 nickels have no clad layers — a copper-colored nickel is always environmental damage, never a "missing clad" error.
Check 3: Dark or Discolored Coin — Almost Always Environmental Damage
Surface color (red, brown, black, dark grey) and texture across the entire coin.
True Improper Annealing is a planchet heated too long in the furnace, turning dark grey or black. The coin would still have smooth, hard, lustrous surfaces with a "cartwheel" light effect and a sharp strike. Very scarce for 1999.
Environmental Damage. Copper in the nickel alloy reacts with soil, soda, and pool chemicals over time, turning the coin dark. Under your 10x loupe: pitting, roughness, and a porous texture mean corrosion — not a mint error. Zero cartwheel luster confirms damage.
Use a 10x loupe to look for surface pitting — pitting confirms environmental damage, not a mint error.

1999 Jefferson Nickel Valuable Errors: Full Diagnostic Guide
Listed highest to lowest value. Each entry covers the error's cause, identification steps, look-alikes to avoid, and verified auction results.
1999 Nickel Bonded / Mated Pair
Left: Normal 1999 nickel. Right: Bonded pair — two coins fused by repeated striking, showing metal flow lines and distorted design.
Origin & Background
Modern coin presses run at high speed. Occasionally a struck coin fails to eject from the striking chamber (the area between the two dies). When the next blank (planchet) is fed in, the dies stamp both the stuck coin and the new blank simultaneously. If this happens repeatedly, coins fuse (bond) together or deform each other into matching (mated) shapes. That any of these escaped the Mint's riddlers — mechanical sorting machines designed to reject misshapen discs — makes them extraordinarily collectible.
How to Identify
- Two or more coins physically fused together, or a single coin crushed into a bottle-cap shape
- Metal flow lines radiating outward from the strike point — structured, not random
- Ghost images of Jefferson's portrait or Monticello stretched across elongated metal
- Mated pairs fit together like puzzle pieces when held against each other
- The coin will not fit in a standard coin roll
False Positives to Avoid
Post-Mint Damage (PMD) — coins hammered flat, run over by a car, or melted with a torch — can look superficially similar. PMD produces random, asymmetric crushing with no metal flow lines and the two pieces will not interlock. Never try to pull a fused pair apart; separating them destroys the provenance and eliminates the premium.
Market Values
- Mated Pair: ~$1,560
- Bonded Cluster (multiple coins): up to $1,750+
Auction Record
$1,750 for a MS-68 Bonded Cluster (NGC; Heritage Auctions archive). A separate Mated Pair sold for $1,560.
1999 Nickel Struck on Dime Planchet (Off-Metal Error)
Left: Standard 21.2mm nickel. Right: Nickel design on 17.9mm dime planchet — note truncated lettering at the edge.
Origin & Background
In 1999, Philadelphia and Denver were simultaneously producing billions of dimes (10¢) and nickels (5¢). If a dime planchet (blank disc) accidentally entered the nickel feeder, the nickel dies would stamp Jefferson's portrait onto the smaller dime disc. The result is a coin with the wrong design-to-size ratio and — crucially — the wrong weight.
How to Identify
- Weight is definitive: must weigh approximately 2.27 grams. A normal 1999 nickel weighs 5.00 grams. Use a digital scale accurate to 0.01g.
- The coin is physically smaller — 17.9mm vs. the standard nickel's 21.2mm
- Design lettering is truncated at the coin's edges ("LIBERT" instead of "LIBERTY")
- Jefferson's portrait and the date are present but cut off near the rim
False Positives to Avoid
"Dryer coins" (tumbled in a clothes dryer until the rim collapses), acid-etched coins, and filed coins may look smaller. These weigh slightly under 5.0g but not at exactly 2.27g. A coin weighing 4.5g or 3.8g is likely damaged. Remember: 1999 nickels are a solid alloy — a copper-colored nickel is environmental damage, never a missing-clad-layer error.
Market Values
- Well-struck example with visible date: $800–$1,500
- Grade and visibility of design details affect price significantly
Auction Record
~$1,400 (estimated from comparable off-metal nickel sales). See PCGS 1999-P Nickel CoinFacts for population and price context.
1999 Major Off-Center Strike (>50%)
A ~75% off-center 1999 nickel — large blank crescent visible, but the date remains readable, preserving the premium.
Origin & Background
This error occurs when the blank planchet is not properly seated in the collar — the ring that centers the coin during striking. The die descends partly on the metal and partly on open air, leaving one side struck with the design and the other as raw, blank metal.
How to Identify
- A visible crescent of blank, unstruck metal on one side of the coin
- The date "1999" must be legible for full value — undated off-centers are worth far less ($5–$15 generic)
- Value by severity: 15–40% off-center = $15–$35; 45–85% with date = $50–$125+; >90% (year unreadable) = $5–$15
- The design flows naturally to the coin's edge with no tool marks or cutting
False Positives to Avoid
Coins clipped or cut after minting (Post-Mint Damage) can mimic an off-center look. Genuine off-center strikes have smooth, natural edges where the design simply fades into the blank area. Clipped coins have straight, mechanically sharp cut edges.
Auction Record
$129 for a 90% off-center example (Heritage Auctions).
1999 Double Struck Nickel
Double struck nickel: two complete design impressions overlap on the same coin at different angles.
Origin & Background
A double-struck coin received two full impressions from the dies. This happens when a struck coin fails to eject and is hit a second time — either in the same position (in-collar) or rotated to a new angle (off-center), producing a dramatic overlapping design.
How to Identify
- Two overlapping impressions of Jefferson's portrait visible on the obverse
- Two overlapping images of Monticello or date numerals on the reverse
- Both impressions show complete die detail — not just thickened letters
- The second strike often partially obliterates the first impression
False Positives to Avoid
Machine Doubling (also called Mechanical Doubling or Ejection Doubling) creates flat, shelf-like steps on letters or the date — it looks like doubling but affects only isolated areas with no depth. A true double strike affects the entire coin with two complete, fully three-dimensional impressions.
Market Values & Auction Record
Value ranges from $50 (in-collar, subtle) to approximately ~$200 for dramatic off-center double strikes. Exact price depends on the rotation angle and visual impact of the second strike.
1999 Broadstrike Nickel
Left: Normal nickel with crisp rim. Right: Broadstrike — oversized diameter, flat rimless edge, design spread outward.
Origin & Background
The collar is a steel ring that encircles the planchet during striking, constraining the metal to the coin's exact diameter and forming the rim. If the collar is jammed open or absent, the metal flows outward unchecked, producing a coin that is wider and flatter than normal with no defined rim.
How to Identify
- Diameter exceeds the standard 21.2mm when measured
- Rim is flat or entirely absent — the field merges smoothly into the coin's edge
- Full design detail is sharp and clear (unlike a damaged coin with washed-out lettering)
- Centered broadstrike (design centered, rim flat): $10–$20
- Uncentered broadstrike (design slightly off + rim flat): $15–$25
False Positives to Avoid
Acid-damaged and heat-damaged coins may appear flat or rimless but have corroded, washed-out design details. Genuine broadstrikes always show sharp, complete design elements throughout.
Auction Record
Approximately ~$35 for a well-centered example. An affordable, accessible entry point for error collectors.
1999 Improper Annealing ("Black Beauty" Type)
Left: Improper annealing — dark but smooth with cartwheel luster. Right: Environmental damage — dark, pitted, and dull.
Origin & Background
Before striking, metal blanks are heated in an annealing furnace to soften them for the press. A planchet left in the furnace too long undergoes a chemical change: copper migrates to the surface, forming a dark gunmetal grey or black layer. Collectors call these "Black Beauties." They are genuine mint errors — but the identical appearance of simple environmental damage makes this one of the hardest errors to confirm.
How to Identify
- Dark gunmetal grey or black coloration
- Surfaces must be smooth, hard, and lustrous — the "cartwheel" light effect (a sweeping reflection when tilted under a light) should be clearly visible
- Strike is sharp with full design detail throughout
- Extremely rare for 1999; treat any claim with healthy skepticism until verified
False Positives to Avoid
Environmental Damage is the #1 look-alike. Nickels buried in soil, left in cup holders with soda, or found in swimming pools turn dark red, brown, or black — but have pitted, rough, porous surfaces and no cartwheel luster. Under a 10x loupe, a damaged coin looks like microscopic sandpaper. An improper annealing error looks glassy and smooth. Also: nickels have no clad layers — a copper-colored nickel is never a missing-clad error.
Market Values & Auction Record
Verified examples: $20–$50. No major confirmed auction record specific to 1999. Values are extrapolated from comparable issues. Professional authentication is strongly recommended before buying or selling.
1999 Doubled Die Variety (DDO / DDR) — Minor Only
The Variety Reality for 1999
A Doubled Die Obverse (DDO) or Doubled Die Reverse (DDR) is created when the hub (master die) impresses the working die more than once at a slightly different angle, embedding split or doubled design elements into the die — and therefore onto every coin it strikes. Famous examples like the 1955 Lincoln Cent DDO or the 1939 Jefferson Nickel DDR are worth thousands.
For 1999, the reality is far more modest. By the late 1990s, the US Mint had largely adopted the "Single Squeeze" hubbing method, sharply reducing the creation of major doubled dies. Specialist references including Variety Vista and Wexler's Doubled Die listings catalog only minor Class VIII varieties for 1999 — microscopic tilted-hub doubling involving slight thickening of letters or a faint secondary thickness on Jefferson's profile. No major recognized DDO or DDR exists for this date that PCGS or NGC attributes at a meaningful premium.
How to Identify Under Magnification
- Use a 10x–20x loupe; look for split serifs or rounded secondary images on the date or motto
- True hub doubling: both impressions are rounded and appear at equal depth — fully three-dimensional
- Machine Doubling (no value): the extra image is flat and shelf-like, one image dropping below the other like a stair step
Market Caution
Be extremely skeptical of online listings titled "RARE 1999 DDO" priced in the hundreds. No PCGS or NGC auction records document significant premiums for 1999 Doubled Dies. These listings almost universally show Machine Doubling or normal die wear masquerading as a variety.
Value & Record
Minor 1999 Class VIII varieties: $1–$5 among specialist collectors. No major auction record. Data confidence for this category is low.
1999-D Repunched Mintmark (RPM)
Origin & Background
A Repunched Mintmark (RPM) occurs when the mintmark punch was applied to a working die more than once, with a slight shift in position, leaving a secondary "D" image visible near or overlapping the primary. RPMs were more common when mintmarks were punched into dies by hand.
How to Identify
- Under 10x magnification: look for a faint secondary "D" offset from or overlapping the primary mintmark
- The secondary image must be consistent and distinct — not general fuzziness or wear
- Applies only to 1999-D (Denver) coins; Philadelphia coins carry no mintmark
- Reference: Wexler's RPM & OMM Varieties →
False Positives to Avoid
Die deterioration causes fuzzy or mushy-looking mintmarks that superficially resemble RPMs. Genuine RPMs show a distinct secondary "D" shape — not just general degradation of the mintmark's edges.
Value & Record
$3–$10 among variety specialists. No major auction record. An interesting addition to a variety collection, but not a financial windfall.
1999 Jefferson Nickel Value Traps: Avoid These Common Mistakes
These are the most frequent reasons collectors believe they have a valuable 1999 nickel — and are wrong. Identify them before spending money on a TPG submission.
Three common types of environmental damage on 1999 nickels — all worth exactly 5¢.
⚠️ Environmental Damage (Disguised as Improper Annealing)
A 1999 nickel that is dark red, brown, black, or dark grey — possibly dug up with a metal detector, pulled from a cup holder, or found in a fountain.
The copper in the nickel alloy reacts with soil acids, carbonated beverages, pool chemicals, and humidity, creating surface oxidation and corrosion.
- Under a 10x loupe: pitting, roughness, or a porous texture = corrosion (environmental damage)
- No cartwheel luster when the coin is tilted under light — genuine Improper Annealing errors always retain smooth, lustrous surfaces
Value: Face value only (5¢).
⚠️ Machine Doubling (Not a Valuable Doubled Die)
Doubled or thickened lettering on the date "1999" or the motto IN GOD WE TRUST — the kind of thing eBay listings brand as "RARE 1999 DDO!"
Machine Doubling (Mechanical or Ejection Doubling) occurs when the die chatters or bounces slightly during or after the strike. It creates flat, shelf-like steps on letters — not the rounded, equal-depth images of a true Doubled Die.
- Under 10x magnification: the extra image is flat and drops below the primary like a stair step
- True Hub Doubling creates two rounded images of equal depth throughout the coin
- No major 1999 DDO has confirmed PCGS/NGC auction records at meaningful premiums
Value: Face value to $5 at most.
Left: Machine Doubling — flat, shelf-like, no value. Right: True Hub Doubling — rounded, separated images. Potentially valuable.
⚠️ "Missing Clad Layer" — Impossible on a Nickel
A 1999 nickel with a reddish-orange or copper-toned appearance, leading you to think the outer layer has peeled off like on a dime or quarter.
Jefferson Nickels are a solid copper-nickel alloy — there are no clad layers to separate. Dimes, quarters, and halves have a copper core bonded between outer layers; nickels do not. The copper appearance is always corrosion.
- A missing-clad-layer error cannot exist on a 1999 Jefferson Nickel — there are no layers to miss
- Copper color on a nickel is exclusively surface corrosion
Value: Face value only (5¢).
⚠️ Pool or Fountain Toning
A 1999 nickel with a distinctive gold, grey, or iridescent sheen, typically found in swimming pools, fountains, or parking lots.
Chlorine and other pool chemicals react with the copper in the nickel alloy, producing a distinctive chemical toning entirely after the coin left the Mint.
- Pool toning is post-mint chemical alteration — classified as damage, not a mint error
- Under magnification, the surface typically shows some pitting or texture change from chemical exposure
Value: Face value only (5¢).
1999 Jefferson Nickel Grading: How Condition Affects Error Values
Coin grading assigns a numerical score from 1 to 70 reflecting a coin's state of preservation. For standard 1999 nickels, grade matters modestly. For major errors, grade can be the difference between $100 and $1,750.
Key Grade Benchmarks
- G-4 to VF-30: Circulated — visible wear on Jefferson's cheekbone and hairlines. Standard 1999 nickels: face value (5¢).
- MS-60 to MS-65: Uncirculated (Mint State) — no wear, full mint luster. Value: $0.25–$1.00.
- MS-66–MS-67 with Full Steps (FS): Premium Mint State. The six steps of Monticello must be completely defined with no breaks or merging. See 1999-P FS PCGS CoinFacts and 1999-D FS PCGS CoinFacts — examples at this level can approach $500+.
- MS-68: The grade of the record-setting Bonded Cluster — $1,750.
ℹ️ Full Steps Is a Condition Award, Not an Error
"Full Steps" (FS) means the coin was well-struck and well-preserved — all six steps of Monticello are intact. A worn nickel without Full Steps is simply circulated. It is not a mint error. Only consider submitting for FS certification if the coin appears MS66 or better, as TPG fees of $30–$60 per coin must be justified by the expected premium.
Auction price history for the 1999-P FS: PCGS Auction Prices 1999-P Full Steps →
1999 Jefferson Nickel Authentication: When to Get Certified
Third-Party Grading (TPG) services like PCGS, NGC, and ANACS authenticate, grade, and encapsulate coins in sealed, tamper-evident holders. Submission typically costs $30–$60 per coin plus shipping. For most 1999 nickels, this cost cannot be justified. For major errors, it is essential.
Stop — Do NOT Submit These
- Dark, discolored nickels with pitted surfaces — environmental damage, not Improper Annealing. Grading fees will far exceed any return (5¢).
- Minor doubling on lettering only — almost certainly Machine Doubling, not a hub variety. No major 1999 DDO has confirmed TPG premium records.
- Standard circulated or uncirculated coins below MS66 — face value or minimal premium. Certification cost is not justified.
Go — Consider Submitting These
- Bonded / Mated Pairs: Do NOT separate them. Submit the pair intact to preserve provenance. Potential value: $1,000–$1,750+.
- Wrong Planchet coins (weight ~2.27g): Certification protects against fraud claims and unlocks full market premium. Potential value: $800–$1,500.
- Major Off-Center Strikes (>50% with visible date): Certified examples achieve higher prices than raw (uncertified) coins.
- Gem-quality MS66+ with Full Steps: If the coin appears flawless with unbroken Monticello steps, certification could unlock $500+.
⚠️ S-Mint Authentication Alert
San Francisco produced only Proof nickels in 1999. If you have a business-strike-looking coin (no mirror fields, no frosted design) with an "S" mintmark, have the mintmark verified before drawing any conclusions. Artificially added mintmarks are a documented fraud in coin collecting.
Looking for a trusted dealer or authentication referral? PCGS and NGC both maintain online directories of authorized dealers who can provide preliminary opinions before a formal TPG submission.
1999 Jefferson Nickel Errors: Frequently Asked Questions
My 1999 nickel is dark or black. Could it be valuable?
Probably not. Use a 10x loupe on the surface. If you see pitting, roughness, or a porous texture, the coin is environmentally corroded — worth 5¢. Only if the surface is smooth, hard, and shows cartwheel luster (a sweeping reflection when tilted under light) despite being dark grey or black does it warrant further attention as a possible Improper Annealing error (worth $20–$50). The vast majority of dark 1999 nickels are environmental damage. Do not clean the coin before examining it.
Is the 1999 Jefferson Nickel rare?
No. Philadelphia struck 1.212 billion and Denver struck 1.067 billion — together over 2.2 billion coins. They are among the most common US coins ever produced. Standard examples are worth face value. Only catastrophic mint errors (bonded pairs, wrong planchets, major off-center strikes) carry significant premiums.
My 1999 nickel looks like it has doubling on the date. Is it a valuable DDO?
Almost certainly not. Under magnification, check if the doubling is flat and shelf-like — one image drops lower than the other like a stair step. That is Machine Doubling, caused by die chatter, not a hub variety. It has no collector premium. True Hub Doubling (a genuine Doubled Die Obverse, or DDO) creates two rounded images of equal depth. No major recognized DDO exists for 1999, and no significant PCGS/NGC auction records confirm premiums for 1999 Doubled Dies. Be very skeptical of high-priced online listings claiming "1999 DDO RARE."
What weight should I look for to find a wrong-planchet error?
A genuine 1999 Jefferson Nickel must weigh 5.00 grams (±0.13g). Use a digital scale accurate to 0.01g. If it weighs approximately 2.27g, it may be struck on a dime planchet (potentially worth $800–$1,500). A reading very close to 5.00g is normal tolerance. A reading between 2.27g and 4.80g typically indicates post-mint damage rather than a planchet error.
Can a 1999 nickel have a missing clad layer?
No. Jefferson Nickels are a solid 75% copper / 25% nickel alloy — not a clad (layered) composition. Only dimes, quarters, half dollars, and dollar coins have clad layers with a visible copper core on the edge. A copper-colored or reddish 1999 nickel is exclusively environmental damage (corrosion), never a missing-clad-layer error.
How much is a 1999-S proof nickel worth?
The 1999-S Deep Cameo Proof was struck in an edition of 3,347,966 for annual Proof Sets. Values range from $2.00–$5.00 in PR65–PR67 and approximately $8.00 in PR69. These are collectible but not rare. If you have an "S" coin that does not have mirror-like fields and a frosted design, have the mintmark verified — S-mint only produced Proofs in 1999.
When is a TPG submission worth the cost for a 1999 nickel?
Consider PCGS, NGC, or ANACS submission (typically $30–$60 per coin plus shipping) only for: bonded/mated pairs (do not separate them first), confirmed wrong-planchet coins that weigh ~2.27g, major off-center strikes over 50% with the date visible, or uncirculated coins that appear MS66+ quality with Full Steps on Monticello. Do not submit dark/discolored coins or coins with only minor doubling — grading fees will far exceed any return.
Is a 1999 nickel with no mintmark a rare variety?
No. Philadelphia Mint 1999 nickels were issued without a mintmark (or with a very small "P" that can be easy to miss). The absence of a visible mintmark is standard for Philadelphia coinage. If the mintmark appears filled or missing due to grease in the die, the coin is worth $1–$2 at most. This is not a rare "No P" variety comparable to the famous 1982-No-P Roosevelt Dime.

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.
