1947 Jefferson Nickel Errors: Value Guide & Rare Varieties
Identify and value 1947 Jefferson Nickel errors: Henning counterfeit ($20–$130+), repunched mintmarks D/D and S/S, doubled dies, and off-center strikes. Expert guide updated January 2026.
Most 1947 Jefferson Nickels are worth $0.05–$0.40 circulated—but the infamous Henning counterfeit fetches $20–$130+, repunched mintmarks add $15–$118, and an MS67 Full Steps specimen can exceed $3,500.
- ⚖️ Weigh it first: 5.0 g = genuine; 5.3–5.4 g = possible Henning counterfeit (worth $20–$130+)
- 🔍 Check the R in PLURIBUS on the reverse: a looped or holed R identifies a 1947 Henning nickel
- 🔎 Examine the D or S mintmark for a doubled impression — RPM-001 D is worth $20–$118; RPM-001 S is worth $17–$40
- 💎 Uncirculated? Inspect Monticello's steps: the Full Steps designation triggers massive premiums
⚠️ Biggest trap: 1947 nickels are NOT silver — the wartime silver alloy ended in 1945. Flat, shelf-like doubling (Machine Doubling) is also worthless.

Most 1947 Jefferson Nickels are common circulation coins worth a few cents—yet this date hides a famous numismatic secret. It hosts the Henning Nickel, America's most notorious collectible counterfeit, which paradoxically sells for more than a genuine specimen. Add verified repunched mintmark varieties, a rare "Best Of" doubled die, and the elusive Full Steps designation, and the 1947 nickel rewards anyone willing to look closely. A digital scale and a 10× loupe are your primary tools. See the complete 1947 Jefferson Nickel value guide →
1947 Jefferson Nickel: Specifications & Baseline Values
Establishing baseline specs is essential for 1947 research. A weight deviation of just 0.3–0.4 grams can signal a famous counterfeit worth ten times a genuine coin.
| Series | Jefferson Nickel |
| Composition | 75% Copper, 25% Nickel — NOT silver |
| Weight | 5.00 g (genuine tolerance: 4.80–5.19 g | Henning counterfeit: 5.27–5.40 g) |
| Diameter | 21.2 mm |
| Edge | Plain (smooth) |
| Mints | Philadelphia (no mintmark), Denver (D), San Francisco (S) — no proofs issued |
Baseline Values by Mint
| Mint | Mintage | Circulated | Typical Mint State |
|---|---|---|---|
| Philadelphia (no mark) | 95,000,000 | $0.05–$0.35 | $1.00–$14.00 |
| Denver (D) | 37,822,000 | $0.05–$0.40 | $1.00–$15.00 |
| San Francisco (S) | 24,720,000 | $0.05–$0.35 | $2.00–$20.00 |
⚠️ The Full Steps (FS) Premium
A Full Steps designation requires all five or six horizontal steps on Monticello's portico to be fully struck and unbroken by weakness or contact marks. Finding one on any 1947 issue is exceptionally difficult. A 1947-S graded MS67 with Full Steps can exceed $3,500. Always check the steps on an uncirculated coin before anything else.
Full Steps (left): five crisp, unbroken step lines. Incomplete steps (right): bridged by strike weakness.

1947 Jefferson Nickel: Quick Checks for Valuable Errors
Run these checks in order. The first two can reveal coins worth $20–$130+; the third flags the traps that waste the most collector time.
Check 1 — The Henning Spot (Philadelphia coins only)
Reverse motto E PLURIBUS UNUM. Focus your loupe on the letter R in PLURIBUS. Also check for a tiny dot in the field above Monticello, just left of the central dome.
A distinct hole or loop inside the legs of the R — it looks like a distorted B. Confirmed by coin weight of 5.27–5.40 g on a digital scale (genuine = 5.00 g). Surface may appear slightly porous or soapy.
A die chip (an irregular raised lump) or post-mint scratches/gouges. A genuine coin has a solid, clean R and weighs exactly 5.00 g. Modern Chinese replicas also exist — compare against known reference photographs.
Check 2 — Repunched Mintmark D/D or S/S (Denver & San Francisco coins)
Reverse, to the right of Monticello, between the building and the rim. Examine the D (Denver) or S (San Francisco) mintmark under 10–20× magnification.
A secondary impression of the mintmark letter: for Denver coins, a second D protruding from the south (RPM-001) or north (RPM-002); for SF coins, a second S to the west (RPM-001) or north (RPM-002). Secondary images are rounded and raised — look for split or notched serifs at the corners of the letter.
Machine Doubling — a flat, shelf-like step that narrows the letter and looks smeared. Die Deterioration — jagged, uneven ridges radiating toward the rim. True RPMs show rounded, raised secondary images that widen the letter dimensions.
Check 3 — Common False Alarms: Silver Claims & Machine Doubling (Traps)
Edge of the coin (silver check) and all lettering including the date and reverse legends (doubling check).
Silver claims: 1947 nickels contain zero silver. Machine Doubling: flat, shelf-like secondary images on lettering that look smeared or slid sideways. Neither adds value.
War Nickels (silver, 1942–1945) have a large mintmark positioned above Monticello's dome. The 1947 nickel's mintmarks are small and positioned to the right of the building. Genuine hub doubling widens letters with rounded, notched images — Machine Doubling narrows them with a flat ledge.

1947 Jefferson Nickel: Rare Errors Worth Real Money
The 1947 Henning Nickel — America's Most Collectible Counterfeit
Genuine R in PLURIBUS (left) vs. Henning counterfeit showing the distinctive loop inside the letter's legs (right).
Origin & Background
Francis LeRoy Henning, operating out of Erial, New Jersey in the mid-1950s, produced nearly half a million counterfeit nickels and injected them into circulation across the Eastern United States. He primarily counterfeited the 1944 nickel (fatally forgetting the required large "P" mintmark, which led to his capture), but also struck dies for 1939, 1946, 1947, and 1953. Today, Henning nickels are actively collected as "contemporary counterfeits" — deliberate fakes from the same era as the genuine coin — and the 1947 issue commands a dedicated following.
How to Identify
- The Looped R (primary marker): On the reverse motto E PLURIBUS UNUM, the letter R in PLURIBUS has a distinct hole or loop joining its legs, making it look like a distorted "B." This resulted from damage to Henning's master die and is the most consistent marker for the 1947 date — though not all Henning dies exhibit it.
- Weight — the most reliable test: Genuine 1947 nickels weigh 5.00 g (range: 4.80–5.19 g). Henning nickels weigh 5.27–5.40 g because his alloy sourcing differed from the US Mint's planchet strip. Use a digital scale with 0.01 g resolution — a kitchen scale rounds to the nearest gram and will miss this.
- Small dot above Monticello's dome: Some Henning dies that lack the Looped R instead show a tiny dot in the field just left of the central dome.
- Surface texture: Henning's inferior manufacturing process often left a slightly porous or "soapy" surface finish — most noticeable on Jefferson's hair detail and Monticello's steps.
Weight test: genuine 1947 nickel at 5.0 g (left scale) vs. Henning counterfeit at 5.4 g (right scale).
False Positives to Avoid
Die chips near the R (irregular, randomly shaped raised lumps) or post-mint scratches can superficially resemble the Looped R. The difference: a genuine die chip is an irregular blob; the Henning loop is a consistent, specific opening inside the letter's legs. Modern Chinese replicas of Henning nickels also circulate — compare surface texture and weight against verified reference photographs at Error-Ref.com.
Market Values
- 🔸 Circulated, confirmed diagnostics: $20–$60
- 🔸 Nice specimen with clear Looped R: $60–$130+
- 🔸 Slabbed by PCGS or NGC as a contemporary counterfeit: premium over raw
Auction Record
~$829 for rare Henning dates at a specialty auction. The 1947 Henning is less common than the 1944 issue but well-recognized by specialists; prices vary based on condition and provenance documentation.
1947 Repunched Mintmarks — D/D and S/S Varieties
In 1947, mintmarks were hand-punched individually into each working die by a mint employee using a mallet and steel punch. If the punch shifted slightly between two blows, a secondary impression was permanently embedded — a Repunched Mintmark (RPM). Look on the reverse, to the right of Monticello.
1947-D RPM-001: a secondary D protrudes below (south) the primary mintmark, with split serifs visible under magnification.
1947-D RPM-001 (D/D South) — Top Denver Variety
- Diagnostic: A secondary D protrudes from the south (bottom) of the primary mintmark. Under 10–20× magnification, look for split serifs on the D and a clear second outline below the primary punch.
- Attribution:VarietyVista 1947-D RPMs
- Value:$20–$50 in MS64/65 | Auction record: $118 at MS65 (GreatCollections)
1947-D RPM-002 (D/D North)
- Diagnostic: Secondary D visible above the primary mintmark to the north (top). Look for serif splitting above the punch under magnification.
- Value:$15–$30
1947-S RPM-001: a second S is visible to the left (west) of the primary mintmark — the top San Francisco variety.
1947-S RPM-001 (S/S West) — Top San Francisco Variety
- Diagnostic: A clear secondary S is visible to the west (left) of the primary mintmark. Listed in CONECA files and VarietyVista. Split serifs are visible under 10× magnification.
- Attribution:VarietyVista 1947-S RPMs · RPM-001 detail page
- Value:$17–$40 in MS63/64 | Auction record: ~$26 at MS65
1947-S RPM-002 (S/S North)
- Diagnostic: Secondary S visible above the primary mintmark to the north (top). Look for serif splitting above the punch.
- Value:$15–$30
False Positives to Avoid
Machine Doubling (MD) creates a flat, shelf-like step that reduces letter width — the mintmark looks smeared or slid sideways. Die Deterioration produces mushy, jagged ridges that radiate unevenly from the letter. Neither is an RPM. Only clear, rounded, raised secondary images with split serifs qualify. Attribution against VarietyVista reference photographs is essential before claiming an RPM.
1947 Doubled Die Varieties — DDR and DDO
A Doubled Die (DDO = Doubled Die Obverse; DDR = Doubled Die Reverse) occurs during die manufacturing: the master hub is pressed into a working die twice with a slight misalignment. This permanently embeds a secondary image into the die, which then appears on every coin struck from it. This is distinct from Machine Doubling, which is a press mechanical defect that happens during striking.
1947 WDDR-001: Class II doubling on FIVE CENTS — letters are noticeably thickened and spread compared to a normal reverse.
1947 WDDR-001 — "Best Of" Doubled Die Reverse (Philadelphia)
- Category: Class II (Distorted Hub) doubling
- Where to look: Reverse legends — FIVE CENTS and E PLURIBUS UNUM. Letters appear significantly thickened with a spread toward the coin's center.
- Significance: Designated "Best Of" in the Wexler files, indicating this is one of the strongest doubled dies known for the 1947 date. Extremely rare and seldom encountered in commerce.
- Key identification test: True hub doubling widens letters with rounded, notched corners. Machine Doubling narrows letters with a flat ledge. If in doubt, the letters of WDDR-001 should appear wider than on a normal coin.
- Value:$50–$150+ for verified examples | Reference: Brian's Variety Coins — 1947 Nickel DDR listings
1947-S WDDO-001 — Doubled Die Obverse (San Francisco)
- Where to look: Obverse — the date, LIBERTY, and IN GOD WE TRUST.
- What counts: Rounded secondary images that increase letter dimensions. Compare to Wexler WDDO-001 reference images for the 1947-S.
- Value:$25–$75
False Positives
Machine Doubling is the primary trap on 1947 nickels and is extraordinarily common due to high production volumes and heavily used dies. Die Deterioration Doubling (DDD) creates ghost-like ridges with jagged, uneven edges radiating toward the rim. Both look like doubling to the untrained eye; neither is a collectible variety. If the doubling looks like pushed or smeared metal with a flat shelf — it is MD, worth face value.
1947 Off-Center Strikes & Broadstrikes
A 1947 nickel off-center strike (~35% off-center). The date remains visible, making this a desirable collector piece.
How to Identify
- Off-Center Strike: The planchet was not centered between the dies, so part of the design is missing. The blank area should be smooth and uniform — if it's rough or torn, it is post-mint damage. The date MUST be visible for significant value; undated off-centers are worth considerably less.
- Broadstrike: The retaining collar (which controls the coin's diameter) was absent during striking. The result is a coin wider than 21.2 mm with a flat or missing rim but a centered design. Coins where the collar was partially deployed are sometimes called "Railroad Rim" errors.
Value by Severity
- 🔸 Broadstrike (centered, full design): $10–$50
- 🔸 Minor off-center (5–10%), date visible: $15–$60
- 🔸 Moderate off-center (15–45%): $30–$125
- 🔸 Major off-center (>50%), date visible: $50–$150+
False Positives
Post-mint damage (PMD) from squeezing, bending, or machining a coin after it left the Mint. A genuine off-center strike shows a uniformly smooth blank planchet where the design is absent — the metal in that area was never struck. PMD typically shows rough, sharp, or distorted edges in the blank zone. A "vise job" (coin deliberately squeezed in a vise) has irregular, non-uniform metal displacement entirely unlike the controlled geometry of a genuine striking error.
1947 Jefferson Nickel: Common Traps & False Alarms
These three traps account for the vast majority of "is this valuable?" questions about 1947 nickels. Recognizing them quickly saves significant time and disappointment.
⚠️ Trap 1: The Silver Myth ("War Nickel" Confusion)
A 1940s nickel that you believe contains silver because it came from the same decade as the wartime silver alloy coins.
The US Mint used a 35% silver alloy (the "War Nickel") only from mid-1942 through 1945. Many collectors assume this applies to all nickels from the 1940s, including 1947.
- War Nickels (1942–1945) carry a large P, D, or S mintmark positioned ABOVE Monticello's dome. The 1947 nickel has no mark or a small D/S to the right of the building — never above the dome.
- The 1947 composition is 75% Copper, 25% Nickel. It has no silver melt value.
- The 1947 nickel is non-magnetic — but so is the War Nickel, so magnetism cannot confirm silver. Check the mintmark position instead.
Value: Standard baseline ($0.05–$0.40 circulated).

⚠️ Trap 2: Machine Doubling (Flat Shelf = Worthless)
The date, Jefferson's profile, or reverse lettering appears doubled — two outlines stacked where one should be.
Machine Doubling (MD) results from mechanical looseness in the press during striking. It is extremely common on 1947 nickels because dies were pushed hard in high-volume production runs. It is not a collectible error.
- Machine Doubling looks like the letter slipped sideways: the secondary image is flat, shelf-like, and the letter appears narrower than normal.
- Genuine Hub Doubling (DDO/DDR) shows rounded, notched secondary images that make letters appear wider than normal. The 1947 WDDR-001 shows a specific spread on FIVE CENTS and E PLURIBUS UNUM.
- If it looks like smeared or pushed metal with a flat ledge — it is MD. Walk away.
Value: Face value only.
Machine Doubling (left): flat shelf, letter appears narrower. Hub Doubling (right): rounded secondary image, letter appears wider.
⚠️ Trap 3: Die Deterioration & Post-Mint Damage
Jagged ridges or "shadows" near letters (Die Deterioration), or a coin with a chunk missing, sharp rough edges, or obviously bent/flattened areas (post-mint damage).
Die Deterioration Doubling (DDD) results from overused, fatigued dies — a product of 1947's heavy production. Post-mint damage (PMD) is any physical harm inflicted on the coin after it left the Mint.
- DDD ridges are jagged and uneven, radiating outward toward the rim — not the clean, rounded split serifs of a genuine RPM or doubled die.
- A genuine clipped planchet requires smooth clip edges and the Blakesley Effect (rim weakness directly opposite the clip), which proves the metal was missing before striking. A rough, sharp-edged missing chunk is PMD.
- A coin squeezed in a vise ("vise job") shows irregular, non-uniform distortion — different from the clean geometry of a genuine broadstrike.
Value: Face value only (DDD); no numismatic value (PMD).
1947 Jefferson Nickel: How Grade Affects Value
Grade — the condition of a coin on the 1–70 Sheldon scale — is the dominant pricing variable for non-error 1947 nickels, and it matters enormously for errors too.
- Circulated (G-4 to EF-45): All three mints are common and affordable. Values spread narrowly — $0.05 to $0.40 — with little premium between grades in this range.
- Mint State MS-60 to MS-65: $1–$20. Strike quality on Monticello's steps becomes the primary separator within this band.
- Gem MS-66+: Significantly scarcer — especially for 1947-S. Even without Full Steps, high-end gems command $50–$200+.
- Full Steps (FS) designation: Requires all five or six horizontal steps on Monticello's portico to be fully defined and unbroken by any strike weakness, contact mark, or planchet flaw. Extremely difficult to find on 1947 issues. A 1947-S graded MS67FS can exceed $3,500.
💡 Never Clean Your Coin
Cleaning a 1947 nickel causes hairline scratches visible under magnification. PCGS and NGC will designate the coin "cleaned" in the holder, which substantially reduces market value. Original surfaces — even dark, toned ones — are always preferable to a bright, cleaned appearance.
1947 Jefferson Nickel: When to Get It Certified
Professional certification through PCGS or NGC involves submitting a coin for authentication, grading, and encapsulation in a tamper-evident holder ("slab"). Submission costs $30–$50+ per coin including return shipping. The economics must justify the fee.
Submit (GO):
- Verified Henning Nickel — Certification authenticates this famous counterfeit, establishes provenance, and protects against modern replicas. A slabbed example designated "contemporary counterfeit" commands a premium over raw coins.
- MS66 or MS67 with Full Steps — The potential value ($3,500+) far exceeds the grading fee. Be strictly honest about step completeness: even one bridge across the steps disqualifies the FS designation.
- 1947 WDDR-001 ("Best Of" DDR) in AU or Mint State — The rarity and low census justify the fee; attribution documentation is critical for this variety.
Do NOT Submit (STOP):
- Minor RPMs valued under $30 — The grading cost exceeds potential return. Attribute and sell raw in 2×2 flip holders with clear photographs.
- Circulated coins with minor errors — The market for low-grade errors is thin and grading fees are rarely recovered.
- Off-center or clipped coins in worn condition — Same economic logic applies unless the error is unusually dramatic or the coin is in high Mint State.
For RPM attribution without full certification, use VarietyVista to compare your coin against diagnostic reference images before committing to submission costs.

1947 Jefferson Nickel Errors: Frequently Asked Questions
Is my 1947 nickel silver?
No. The silver "War Nickel" alloy (35% silver) was used only from mid-1942 through 1945. The 1947 Jefferson Nickel is 75% Copper and 25% Nickel — no silver content whatsoever. The fastest check: War Nickels have a large mintmark positioned above Monticello's dome; 1947 nickels have no mark or small D/S marks to the right of the building, never above the dome.
How do I identify a Henning nickel?
Use two tests: (1) Weight — genuine nickels weigh 5.00 g; Henning nickels weigh 5.27–5.40 g. A digital scale with 0.01 g precision is required. (2) Visual — under 10× magnification, examine the letter R in PLURIBUS on the reverse motto E PLURIBUS UNUM. A loop or hole inside the letter's legs is the primary Henning marker. Some Henning dies also show a small dot in the field above Monticello's dome, just left of center.
What is the most valuable 1947 nickel?
For non-error coins, a 1947-S graded MS67 with the Full Steps designation can exceed $3,500. Among errors, the Henning counterfeit leads at $20–$130+ (with rare Henning dates reaching ~$829 at specialty auction). The 1947 WDDR-001 "Best Of" Doubled Die Reverse is extremely rare and commands $50–$150+ when verified; the 1947-D RPM-001 has sold for $118 at MS65.
What does "Full Steps" mean, and why does it matter so much?
Full Steps (FS) refers to the five or six horizontal steps leading up to Monticello's portico on the reverse. For the designation, every step must be fully defined — unbroken by any strike weakness, contact marks, or planchet imperfections. Because Philadelphia and Denver mint dies were often pushed past their optimal life in 1947, and San Francisco strike quality varied, a fully struck set of steps is extremely rare. The jump in value from a non-FS to FS coin in MS67 can be thousands of dollars.
What is Machine Doubling, and why is it worthless?
Machine Doubling (MD) results from mechanical looseness in the press during the strike — the die bounces slightly and creates a flat, shelf-like secondary image. Letters appear narrower and smeared, as if pushed sideways. It is extremely common on 1947 nickels due to high production volumes and is entirely without collector value. Genuine hub doubling (DDO/DDR), created during die production, shows rounded, notched secondary images that widen the letters — the opposite appearance.
How do I attribute a 1947 Repunched Mintmark?
Under 10–20× magnification, examine the D or S mintmark on the reverse (to the right of Monticello). Look for split or notched serifs — the corners of the letter appear doubled — and a secondary letter image protruding north, south, or west of the primary punch. The key: secondary images must be rounded and raised, not flat. Compare your coin against reference photographs at VarietyVista 1947-D or VarietyVista 1947-S before claiming an RPM.
Should I clean my 1947 nickel before submitting it?
Absolutely not. Cleaning produces microscopic hairlines clearly visible under a grading service's loupe. PCGS and NGC designate cleaned coins in the holder (e.g., "Cleaned" or "Whizzed"), which drastically reduces auction results and resale value. Original surfaces — even dark, toned ones — are always more desirable to serious collectors than a bright cleaned appearance.
How do I verify a clipped planchet is genuine (not damage)?
A genuine clipped planchet has two telltale signs: (1) Smooth clip edges — the clipped area has a smooth, rolled edge, not a rough or sharp cut. (2) The Blakesley Effect — a weakness in the rim directly opposite the clip. This rim weakness occurs because the clip prevented the metal from flowing properly into the collar on that side. If both signs are present, the clip is genuine. A rough, jagged missing chunk with sharp edges is almost always post-mint damage.
