1939 Lincoln Wheat Cent Errors: Value Guide & Rare Varieties
What is your 1939 Lincoln Wheat Cent error worth? The DDO FS-101 doubled die sells for $25–$2,350. Full guide to RPMs, off-centers, broadstrikes, proofs, and how to avoid machine doubling traps.
Most 1939 Lincoln Wheat Cents are worth only $0.05–$0.50 in circulated grades, but the Doubled Die Obverse FS-101 is worth $25–$2,350 and authentic Proof examples fetch $150–$300+.
- 🔍 Top variety: DDO FS-101 — split serifs on LIBERTY, worth $25 circulated up to $2,350 in MS67+ Red.
- 💰 Auction record: $2,350 for a 1939 DDO FS-101 in MS67+ RD (Heritage Auctions).
- 📜 Proof: Only 13,520 struck — mirror-like fields and squared rims signal $150–$300+ value.
- 🏷️ 1939-D semi-key: Just 15.1 million minted; worth $15–$45 uncirculated.
⚠️ Biggest trap: Machine Doubling — flat, shelf-like steps on the date and profile — looks exactly like a doubled die but adds zero numismatic value. See the Traps section to learn the difference.

Values shown are typical retail estimates as of 2026-01.
Error coin values vary significantly based on grade, color designation (RD/RB/BN), eye appeal, and current market conditions.
Professional authentication (PCGS/NGC) is recommended for high-value varieties, especially the 1939 DDO (FS-101).
Machine Doubling (flat, shelf-like) is NOT a valuable doubled die — it adds zero numismatic value.
No genuine 1939 Lincoln Cent is magnetic or silver-colored. Silver-colored 1939 pennies are post-mint alterations (plating or chemical treatment).
Die Deterioration (flow lines, ghosting of Lincoln's bust on reverse) is a sign of die overuse, not a valuable error.
The 'L' in LIBERTY touching the rim on 1930s cents is a design characteristic, not a valuable error.
Open a roll of old Lincoln cents and you might be sitting on more than pocket change. The 1939 Lincoln Wheat Cent ranges from a $0.05 circulated coin all the way to $2,350 for the right variety in top condition — a difference that lives in the serifs of a single letter. This guide at coins-value.com walks you through every valuable 1939 error, exactly what to look for with a loupe, and the traps that fool even experienced collectors.
1939 Lincoln Wheat Cent: Specifications & Mintage by Mint
Before hunting errors, confirm what a normal 1939 cent looks and feels like. Any coin that is magnetic, weighs significantly outside the normal range, or appears silver-colored is a post-mint alteration — not a valuable error.
| Specification | Detail |
|---|---|
| Series | Lincoln Wheat Cent (Wheat Reverse) |
| Composition | 95% Copper, 5% Tin & Zinc (French Bronze) |
| Weight | 3.11 g (tolerance: 2.98–3.24 g) |
| Diameter | 19.00 mm |
| Edge | Plain |
| Magnetic? | No — any 1939 penny that sticks to a magnet is a post-mint alteration |
| Silver-colored? | No — there were no steel cents in 1939; silver color = post-mint plating |
Mintage & Value by Mint
The most common 1939 cent. Very high mintage makes circulated examples worth just $0.05–$0.15. Uncirculated (MS63–65) coins run $5–$12. Full Red (RD) examples in MS66–67 climb sharply. Only Philadelphia struck the valuable DDO FS-101 — always check this mint for split serifs on LIBERTY.
A semi-key date — the lowest-mintage 1939 business strike. Worth $0.10–$0.50 circulated and $15–$45 in MS63–65. MS67+ populations drop sharply, creating genuine condition rarities. Check for the D/D Repunched Mintmark (RPM-001) variety below the date.
Common in lower grades ($0.10–$0.30 circulated) but difficult to find with fully struck details — San Francisco used lower die pressures, making sharp examples scarce. Worth $10–$25 in MS63–65. Check for the S/S Repunched Mintmark (RPM-001) variety below the date.
1939 Proofs were sold directly to collectors and never intended for circulation. Genuine Proofs have squared, wire-like rims and mirror-like fields. Cameo examples (frosted Lincoln against mirror background) are especially rare. A merely shiny coin is almost certainly a polished business strike — damaged, not valuable.

1939 Lincoln Cent Quick Checks: Do You Have Something Valuable?
Grab a 10x loupe — a small magnifying glass used by jewelers and coin collectors, available for $10–$20. The difference between a $500 coin and a $0.05 coin is often invisible to the naked eye.
Check 1 — Doubled Die Obverse FS-101 (Philadelphia / No Mint Mark Only)
Focus your loupe on the word LIBERTY — specifically the letters B, E, R, T, and Y — and the date 1939. This variety occurs only on Philadelphia coins (no mint mark below the date).
A clear rotational spread on the letters. Look for split serifs — V-shaped notches at the bottom corners of letters where two overlapping images diverge. The pivot point is near 10 o'clock, so doubling is strongest on LIBERTY and the date. The doubling adds to letter width.
Machine Doubling (MD) — flat, shelf-like ledges that reduce letter width. If the doubling disappears when you tilt the coin, or looks like a staircase step, it is worthless MD. See Traps.
Check 2 — Repunched Mintmark S/S RPM-001 (San Francisco Only)
Inspect the S mintmark located directly below the date 1939. San Francisco coins only.
A secondary S outline peeking out from underneath or beside the primary S. The punch was applied to the working die multiple times at slightly different angles. Split serifs on the S are the primary diagnostic.
Die Deterioration Doubling — a bloated or ghostly shadow on the mintmark that flows uniformly toward the rim is die wear, not an RPM. PCGS does not list 1939-S RPMs as primary registry varieties.
Check 3 — Repunched Mintmark D/D RPM-001 (Denver Only)
Inspect the D mintmark directly below the date 1939. Denver coins only.
A secondary D outline visible underneath or beside the primary D — a D-over-D effect where the punch was applied multiple times at slightly different positions.
Die Deterioration Doubling — a bloated shadow flowing radially toward the rim is die wear. PCGS does not list 1939-D RPMs as primary registry varieties; the premium is modest.
Check 4 — Common Misidentifications (All Mints — TRAPS)
The entire coin surface — especially the date, Lincoln's profile, and the rim text IN GOD WE TRUST.
True off-center strikes (clean blank crescent at edge, design shifted) and genuine clipped planchets (smooth curved bite with weak rim opposite). These ARE valuable. Everything else below is a trap.
Machine Doubling (flat shelf-like steps), Die Deterioration (fuzzy radial flow lines or the Ghost of Lincoln visible on the reverse), and silver-colored 1939 pennies (post-mint plating) are NOT valuable errors.

1939 Lincoln Cent Valuable Errors & Varieties: Detailed Identification Guide
1939 Doubled Die Obverse — FS-101 (DDO-001)
Normal 1939 cent (left) vs. DDO FS-101 (right) showing the rotational split on LIBERTY.
Origin & Background
In 1939, working dies were created by pressing a master hub (the engraved master template) into a steel blank — a process requiring multiple squeezes. Between squeezes, the die was removed and annealed (softened with heat). If it was not perfectly re-aligned with the hub for the next squeeze, a doubled image was locked permanently into the die. For the FS-101, the misalignment had its pivot point near 10 o'clock. In pivoted hub doubling, the further a design element is from the pivot point, the stronger the separation — which is why LIBERTY and the date show the most dramatic doubling.
How to Identify
Split serif V-notch at the base of the B and R in LIBERTY — the definitive FS-101 diagnostic.
- LIBERTY: Look for a clockwise rotational spread. The definitive pick-up point is V-shaped notches (split serifs) at the bottom corners of letters B, E, R, T, and Y — where the two impressions of each letter visibly separate.
- Date 1939: The digits may show widening or separation, with a secondary image visible at a slight rotational offset.
- IN GOD WE TRUST: Doubling is also visible here, particularly on the word TRUST.
- Early vs. Late Die State: Early die state (EDS) examples show crisp, sharp separation. Late die state (LDS) examples have mushier doubling with possible die scratches or flow lines that can obscure the separation, making authentication harder.
- Tool required: 10x loupe minimum. The split serifs are often too small to confirm with the naked eye.
False Positives to Avoid
Machine Doubling (MD) is the single biggest false alarm. MD creates a flat, shelf-like ledge extending from the side of a letter — like a staircase step. It reduces letter width while true DDO adds width. Tilt the coin: MD flattens out under raking light; DDO doubling retains a rounded, three-dimensional character. Always compare against the official PCGS CoinFacts diagnostic images at PCGS #37777.
Market Values
- 📍 VF (Very Fine, circulated):$25
- 📍 XF (Extremely Fine):$40–$75

1939-S & 1939-D Repunched Mintmarks (RPM-001)
Normal 1939-S mintmark (left) vs. RPM-001 S/S with secondary S impression visible at lower right (right).
Origin & Background
A Repunched Mintmark (RPM) occurs when the mintmark punch — the handheld tool used to stamp the D or S into the working die — was applied multiple times at slightly different positions or angles. Both the Denver (D/D) and San Francisco (S/S) 1939 issues have recognized RPM-001 varieties documented by VarietyVista and CONECA. Critically, PCGS does not list these as primary registry varieties, which limits their market to specialist variety collectors. The premium over a generic same-grade example is real but modest.
How to Identify
Normal 1939-D mintmark (left) vs. RPM-001 D/D showing secondary D impression at upper left (right).
- 1939-S RPM-001: Under 10x–20x magnification, look for a secondary S outline peeking from underneath the primary S, or split serifs at a different angle from the main mintmark. Reference: VarietyVista 1939-S Lincoln Cent RPMs.
- 1939-D RPM-001: Look for a secondary D outline at a slightly different position — a D-over-D effect with the secondary impression offset above, below, or to one side.
- Tool required: 10x–20x loupe for definitive identification.
False Positives to Avoid
Die Deterioration Doubling causes a bloated or ghostly shadow on the mintmark that flows radially toward the rim. This is simply die overuse — not an RPM. The flow lines extend outward uniformly; a true RPM shows a distinct secondary impression at a different angle, not a gradual bleed.
Market Values & Auction Records
- 📍 1939-S RPM-001, AU:$5
- 📍 1939-S RPM-001, MS65:$20–$40
- 📍 1939-S RPM-001, MS66 (record):~$40
- 📍 1939-D RPM-001, AU:$5
- 📍 1939-D RPM-001, MS65:$20–$30
A generic 1939-S in the same grade is already $10–$25, so the RPM premium is roughly $10–$20. Manage expectations accordingly.
1939 Off-Center Strikes
1939 off-center strike (~30%) showing visible date and blank crescent at right edge.
Origin & Background
An off-center strike occurs when a coin blank is not centered in the retaining collar at the moment of striking. The result is a crescent of unstruck, blank metal at one edge. The 1939 date must remain visible for the coin to command premium prices — without it, the coin cannot be definitively attributed and is worth only $5–$15 as a generic wheat cent error.
Value by Percentage Off-Center
| % Off-Center | Notes | Value Range |
|---|---|---|
| 1%–10% (Minor) | Often dismissed; may look like a misaligned die | $10–$35 |
| 10%–25% (Moderate) | Good eye appeal; entry-level error collector piece | $50–$125 |
| 30%–60% (Major) | "Bullseye" appearance; date must be clear | $150–$350+ |
| >60% (No Date) | Cannot verify as 1939; generic wheat cent error | $5–$15 |
False Positives to Avoid
A Misaligned Die (MAD) shifts one die slightly relative to the other, creating a minor offset that is much less dramatic than a true off-center. Post-mint damage from bending or folding does not create a smooth blank crescent — tool marks and uneven metal flow will be visible under a loupe.
Auction Record
~$370 for an off-center / brockage example (Heritage Auctions).
1939 Broadstruck Errors
1939 broadstruck cent showing design spreading beyond the standard 19mm diameter, rim absent.
Origin & Background
A broadstrike occurs when the retaining collar — the ring that molds the planchet into a perfectly round coin during striking — fails to deploy. Without it, the metal flows outward freely, producing a wider-than-normal "pancake" appearance with a distorted or absent rim. Unlike an off-center strike, the design remains centered; it simply spreads out.
How to Identify
- Measure diameter with calipers — a genuine broadstrike will exceed the standard 19.00 mm.
- The rim will be absent or severely distorted around the full perimeter.
- The design spreads outward but should remain complete and centered.
- Consistent thickness throughout the coin (unlike a hammered or run-over coin).
False Positives to Avoid
Post-mint damage from a vehicle running over the coin can mimic a broadstrike, but will show uneven thickness, scrape marks, and distortion inconsistent with a clean single-strike. A genuine broadstrike will have uniform thickness and no tool marks.
Auction Record
~$400 (estimated asking price; no confirmed auction record in source data).
1939 Clipped Planchet Errors
1939 clipped planchet showing the curved "bite" (left) and the weak rim at the opposite side — the Blakesley Effect (right).
Origin & Background
Clipped planchets occur before minting, when the machine that punches circular coin blanks from a metal strip overlaps a previously punched hole. The result is a curved "bite" missing from the coin's edge. Because this happens to the blank, not just the strike, both the hole and the corresponding weak area on the opposite side are authentic mint characteristics.
The Blakesley Effect — The Critical Authentication Test
- Look at the rim directly opposite the missing clip. On a genuine clipped planchet, the rim there will be weak, tapered, or indistinct. This is the Blakesley Effect: the missing metal at the clip site prevented the upsetting mill from exerting full pressure on the diametrically opposite side.
- If the rim opposite the clip is sharp, full, and normal — the "clip" is post-mint damage (shears or wire cutters). Not a genuine error.
- The clipped edge itself should be smooth and unstruck, not rough or jagged.
Value by Clip Size
| Clip Size | Notes | Value Range |
|---|---|---|
| Small (<5% of coin) | Common; often mistaken for damage by novices | $3–$8 |
| Medium (5–15%) | Must show Blakesley Effect to authenticate | $10–$25 |
| Large (>15%) | Rarer on pre-war copper than on modern zinc cents | $30–$75 |
Auction Record
~$8 for a circulated clipped planchet example (confirmed sold).
1939 Lincoln Cent Value Traps: Don't Be Fooled
These are the most common false alarms for 1939 Lincoln Cents. Recognizing them could save you a $30–$60 grading fee on a coin worth face value.
⚠️ Trap 1: Machine Doubling — The #1 False Alarm
A stepped, doubled appearance on the date and Lincoln's profile — looks convincingly like a real doubled die at first glance.
In 1939, the Mint was running dies through high production volumes. Loose die settings caused the die to bounce or slide slightly as it retracted after striking, smearing the design into a flat secondary image.
- The doubling is flat and shelf-like — like a staircase ledge extending from the side of a letter, not a rounded second image.
- It reduces the apparent width of letters; true DDO doubling adds width.
- Tilt the coin under raking light: MD flattens out; DDO retains depth and notching.
- No V-shaped split serifs at letter corners — just a flat smear.
Value: Face value only. Zero numismatic premium.
Machine Doubling (left, flat shelf step) vs. genuine DDO FS-101 (right, rounded notch). Value difference: $0 vs. $25+.
⚠️ Trap 2: Die Deterioration — "The Ghost of Lincoln"
Radial streaks (flow lines) across the obverse surface, or a faint ghostly outline of Lincoln's bust visible on the reverse (Wheat side) of the coin.
1939 dies were often used far past their optimal lifespan to meet production demand. Worn die surfaces develop erosion grooves, and metal flows into those grooves during striking, creating ghost images and radial patterns on the coin.
- Flow lines radiate uniformly from center outward — not a crisp secondary doubled image.
- The "ghost" on the reverse is faint and indistinct, not a sharp second strike.
- This is considered a quality defect and can actually reduce eye appeal and collector value.
Value: Slightly below normal for the grade. Not a valuable error.
⚠️ Trap 3: "Silver" 1939 Pennies — Post-Mint Plating
A 1939 Lincoln cent that appears silver, white, or nickel-colored instead of copper-bronze.
Electroplating — a common chemistry class or novelty treatment — coats a copper cent with zinc, nickel, or mercury. There were no steel or silver cents in 1939. The only steel cent was a one-year type in 1943.
- Weigh it: a genuine plated-copper 1939 cent still weighs ~3.11 g. A genuine 1943 steel cent weighs 2.7 g. If it weighs ~3.1 g, it is plated copper.
- Test with a magnet: copper is non-magnetic. If it attracts strongly to a magnet, it is a plated 1943 steel cent with a possibly altered date.
- Look for uneven plating, bubbles, or copper showing through at wear points.
Value: Face value only. Post-mint alterations are not genuine errors.
⚠️ Trap 4: The "L" Touching the Rim
The letter L in LIBERTY appears to touch or merge with the coin's rim.
This is a normal design characteristic and die setting feature appearing on a very large proportion of 1930s–1940s Lincoln cents. It is not a unique error, die variety, or cud.
- It appears on the vast majority of 1939 cents — far too common to be a variety.
- A genuine cud error (raised blob of metal at the rim from a broken die chip) looks dramatically different and completely obliterates the design in one localized area.
Value: Face value only.
1939 Lincoln Cent Grading: How Condition & Color Control Value
For 1939 Lincoln cents, value is controlled by two factors: numerical grade and color designation. Both matter enormously — especially for the DDO FS-101.
Numerical Grade (Sheldon Scale)
Grades run from 1 (barely identifiable) to 70 (theoretically perfect). Circulated 1939 cents fall from Good-4 (G-4) through About Uncirculated-58 (AU-58). Uncirculated coins are Mint State (MS): MS-60 through MS-70. For the DDO FS-101, even a VF-20 (Very Fine — moderate wear, design still clear) commands $25+. For plain business strikes, only MS-65 and above carry meaningful premiums over baseline.
Color Designation — Critical for Copper Cents
All Mint State Lincoln cents receive a color designation based on how much original copper luster survives:
- RD (Red): 95% or more original red copper luster intact. Commands the highest prices. Do not touch surfaces with bare fingers — skin oils begin destroying RD status immediately.
- RB (Red-Brown): Partial original luster (5–95%). Mid-range value.
- BN (Brown): Fully toned; no remaining red luster. Lowest prices in the same grade. The DDO FS-101 in MS67 BN sold for ~$463; the identical grade in RD realized $2,350 — a 5× difference from color alone.
Left to right: 1939 Lincoln cent in BN, RB, and RD. Color designation alone creates a 5× value difference for the DDO FS-101.
⚠️ Never Clean Your Coin
Cleaning permanently and irreversibly damages a coin's surfaces, destroying any Red designation. A cleaned MS-65 RD becomes an uncertifiable "details" coin worth a fraction of its original value. Store in a 2×2 Mylar flip or original PCGS/NGC holder — never PVC plastic (damages copper), never bare fingers on surfaces.
1939 Lincoln Cent Authentication: When to Get It Certified
Professional certification by PCGS or NGC permanently identifies, grades, and protects your coin's value. Grading fees typically run $30–$60+ per coin, so the math must work in your favor before submitting.
Required Tools Before You Submit
- 10x–20x loupe: Non-negotiable. You cannot confirm split serifs — the FS-101's defining diagnostic — without it.
- 0.01g digital scale: Verifies genuine weight (~3.11 g). A coin weighing 2.2–2.8 g may be a rolled-thin planchet error (worth investigating); under 2.0 g is likely acid-damaged (worthless).
✅ Submit for Grading
- Confirmed DDO FS-101: If you clearly see split serifs on LIBERTY matching the FS-101 diagnostic. PCGS attribution as #37777 maximizes market liquidity and confirms authenticity to buyers.
- Gem Red (MS65+ RD): Coin has no spots, full original red luster, and appears nearly brand-new.
- Major Mint Error: Dramatic off-center or broadstrike with clear 1939 date and original Red color.
- Possible Proof: Mirror-like fields and squared rims — professional authentication is essential given the $150–$300+ value at stake.
❌ Do NOT Submit
- Machine Doubling: The grading fee will far exceed any premium. Do not submit.
- Environmental damage: Verdigris (green corrosion), dark spotting, or hairline scratches from cleaning will result in a "details" holder worth less than grading cost.
- Minor errors: A small clip (<5%) or minor lamination will not generate enough premium to justify encapsulation costs.
💡 Strategy Tip
Before paying grading fees, verify your coin against the official PCGS CoinFacts diagnostic images at pcgs.com/coinfacts/coin/1939-1c-ddo-fs-101-rd/37777. If your coin's split serifs clearly match, PCGS certification as variety #37777 is the gold standard for resale.

1939 Lincoln Cent Errors: Frequently Asked Questions
What is the most valuable 1939 Lincoln penny error?
The 1939 Doubled Die Obverse FS-101 (DDO-001) is the undisputed king of 1939 varieties. It sold for $2,350 in MS67+ Red at Heritage Auctions. Even in circulated grades like VF, it commands $25+. It occurs only on Philadelphia (no mint mark) coins and is certified by PCGS as variety #37777.
How do I tell a genuine doubled die from machine doubling on a 1939 penny?
True Doubled Die Obverse (DDO) doubling is rounded and adds width to the letters — look for V-shaped notches (split serifs) at the corners of letters in LIBERTY, where two overlapping images diverge. Machine Doubling (MD) is flat and shelf-like, like a staircase step extending from the letter edge, and it reduces apparent letter width. Tilt the coin under raking light: MD flattens out; DDO retains three-dimensional depth. MD adds zero value; DDO FS-101 is worth $25+ even circulated.
What is a 1939 Proof cent and how can I tell if I have one?
Only 13,520 Proof cents were struck at Philadelphia in 1939, sold directly to collectors. Genuine Proofs have squared, wire-like rims and highly mirror-like fields (backgrounds). Cameo examples — frosted Lincoln portrait against a mirror background — are especially rare and valuable. A "shiny" ordinary cent is almost certainly a polished business strike (damaged and worthless as a Proof). In PR65 they are worth $150–$300+. Professional authentication by PCGS or NGC is strongly recommended.
Is the 1939-D penny worth more than the Philadelphia cent?
Yes, somewhat. Denver struck only 15.16 million cents vs. Philadelphia's 316 million. The 1939-D is a semi-key date: $0.10–$0.50 circulated (vs. $0.05–$0.15 for P) and $15–$45 uncirculated (vs. $5–$12 for P). In MS67+ it becomes a genuine condition rarity as populations drop sharply. However, the Philadelphia DDO FS-101 is worth many multiples more than any 1939-D variety.
Why is my 1939 penny silver or white-colored?
No genuine 1939 Lincoln cent is silver or white. There were no steel cents in 1939 — that was an emergency wartime measure used exclusively in 1943. A silver-colored 1939 penny is a post-mint alteration, most likely electroplated zinc or nickel as a chemistry experiment or novelty item. Confirm: weigh it (~3.11 g if copper, not ~2.7 g like a genuine steel cent); test with a magnet (copper is non-magnetic). Post-mint alterations have no numismatic value beyond face value.
What do RD, RB, and BN mean and why do they matter so much?
These are color designations applied to all Mint State copper cents: RD (Red) = 95%+ original copper luster remaining, highest value; RB (Red-Brown) = partial luster, mid-range value; BN (Brown) = fully toned, lowest value for the same grade. For the DDO FS-101, MS67 RD sold for $2,350 vs. ~$463 for MS67 BN — a five-fold difference solely from color. Never clean your coin; cleaning permanently destroys RD status and makes the coin essentially unsellable to serious collectors.
What tools do I need to check my 1939 penny for errors?
Two tools are essential: (1) A 10x–20x loupe — required to see split serifs on the DDO FS-101 and distinguish genuine RPMs from die deterioration. A 10x jeweler's loupe costs $10–$20 and is non-negotiable for variety hunting. (2) A 0.01g digital scale — to verify the coin weighs ~3.11 g, ruling out counterfeits and identifying planchet errors (a rolled-thin planchet weighs 2.2–2.8 g; acid-damaged coins weigh under 2.0 g).
Can I still find valuable 1939 error cents in old rolls or bulk lots?
The DDO FS-101 is a recognized Cherrypickers' Guide variety that collectors have actively sought for decades, so most high-grade certified examples have already been found. However, bulk rolls of old wheat cents occasionally yield uncertified circulated specimens — even a VF example is worth $25 if correctly attributed. Look for coins with clean fields, no obvious cleaning, and the diagnostic split serifs on LIBERTY. The 1939 cent's high Philadelphia mintage (316 million) means there are still many unexamined examples in old collections.

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.
