Most 1943 steel pennies are worth between $0.10 and $3.00 in typical circulated condition. They are common coins — nearly 1.1 billion were struck across three mints — and their collector value depends almost entirely on mint mark and grade. The 1943 copper cent is a different story entirely: genuine copper examples are among the most valuable US coins ever discovered, with prices well into six figures.
Why 1943 Pennies Are Steel
During World War II, the US War Production Board designated copper as a critical war material needed for shell casings, radio components, and other military equipment. Starting in 1943, the US Mint struck Lincoln cents from zinc-coated low-carbon steel instead of the normal 95% copper alloy.
The composition of the 1943 steel cent:
- Core: low-carbon steel
- Coating: zinc (thin electroplated layer)
- Weight: 2.70 g
- Diameter: 19.05 mm
The coins were unpopular with the public. They were easily confused with dimes, they rusted when the zinc coating wore through, and vending machines sometimes rejected them. The Mint returned to copper in 1944, using salvaged shell casings from the war effort — which is why 1944–1946 cents have a slightly different composition (95% copper, 5% zinc rather than the pre-war tin alloy).
Value by Mint Mark and Grade
Three facilities struck steel cents in 1943. The Philadelphia Mint produced the most; San Francisco struck the fewest, making the 1943-S the most valuable of the common steel cents.
| Coin | Mintage | VG-8 | Fine-12 | EF-40 | MS-63 | MS-65 |
|---|---|---|---|---|---|---|
| 1943 (Philadelphia) | 684,628,670 | $0.20 | $0.35 | $1.00 | $8 | $35 |
| 1943-D (Denver) | 217,660,000 | $0.35 | $0.60 | $2.00 | $12 | $55 |
| 1943-S (San Francisco) | 191,550,000 | $0.50 | $0.75 | $3.00 | $18 | $75 |
Grade abbreviations: VG = Very Good, EF = Extremely Fine, MS = Mint State (uncirculated). Values are approximate retail based on recent auction data and dealer price guides; always verify against current PCGS or NGC population data and recent sales before buying or selling.
Coins that show obvious rust or heavy corrosion sell at the low end or below. The zinc coating on steel cents is thin and often worn through on circulated examples, exposing the steel to oxidation. Rust significantly reduces value.
How to Identify a Genuine 1943 Steel Cent
A genuine 1943 steel cent will:
- Stick to a magnet. Steel is ferromagnetic. Hold any magnet close and the coin should snap to it immediately. This is the single most reliable identification test.
- Show a gray, slightly silvery surface — not the warm reddish-brown of copper. Heavily circulated pieces often show rust patches.
- Weigh 2.70 g on a precise scale. This is different from the post-1982 zinc cent (2.5 g) and the copper cent (3.11 g).
The Rare Error: 1943 Copper Cents
A small number of copper planchets (coin blanks) left over from 1942 production were not removed from the presses before the 1943 steel planchets were loaded. These bronze planchets were accidentally struck with the 1943 dies, creating what collectors call the 1943 copper cent.
Key facts about 1943 copper cents, based on PCGS population data and Heritage Auctions sale records:
- Philadelphia (no mint mark): approximately 10–15 known examples authenticated by PCGS/NGC; values vary widely by grade — consult current PCGS or NGC price guides for certified examples
- Denver (1943-D): one example is confirmed by PCGS; Heritage Auctions records a sale of a PCGS MS-64 BN example for $1,700,000 in January 2010 (Heritage lot 4276, FUN sale)
- San Francisco (1943-S): a small number of examples are known in PCGS/NGC holders; values for certified examples should be verified against current auction records at Heritage Auctions or Stack’s Bowers
How to check if your 1943 cent might be copper:
- Hold a magnet near it. If it does not stick, proceed.
- Check the date and composition feel — genuine copper coins have a warmer, yellower tone than steel.
- Check the weight: a copper cent weighs 3.11 g; a zinc-plated lead copy (common fakes) will weigh differently.
- Have it authenticated by PCGS or NGC before assuming it has high value. Altered coins — steel cents coated in copper plating — are common fakes. Only a certified slab provides reliable authentication.
Never clean or polish a suspected 1943 copper cent. Cleaning destroys numismatic value and makes authentication harder.
1944 Steel Cents — The Reverse Error
In 1944, after switching back to copper, a small number of steel planchets were again left in the presses and struck with 1944 dies. These 1944 steel cents are also extremely rare and valuable:
- 1944 (Philadelphia): about 25 known; values typically $75,000–$150,000
- 1944-D: fewer than 10 known; $175,000+
- 1944-S: one or two known
A 1944 cent that sticks to a magnet warrants immediate professional authentication.
Melt and Scrap Value
Unlike the pre-1982 copper penny, the 1943 steel cent has negligible commodity value. Steel and zinc are common industrial metals worth fractions of a cent per gram. The melt value of a 1943 steel cent is essentially zero from a practical standpoint, and melting US coins is prohibited by 31 CFR Part 82 regardless.
The coin melt value calculator covers copper, silver, and gold coins. Steel cents are not included because the metal value is below face value.
Frequently Confused Coins
- 1943 aluminum cents: These do not exist as official US Mint issues. A few pattern (test) pieces were struck in aluminum in 1974 — not 1943. Any “1943 aluminum penny” is fake.
- Silver 1943 cents: Genuine 1943 steel cents can appear silver-toned from fresh zinc plating. They contain no silver. The coating is zinc, not silver.
- Painted or plated fakes: Common scams involve copper-plating genuine steel cents or acid-washing cents to alter the surface. A magnet test quickly exposes copper-plated steel fakes (they still stick).
Practical Advice
If you find a 1943 cent in a roll or jar:
- Test it with a magnet immediately.
- If it sticks, it is a common steel cent worth under $5 in typical condition.
- If it does not stick, do not spend it, clean it, or attempt to identify it yourself. Place it in a soft coin flip and take it to a local coin dealer or submit it to PCGS or NGC for authentication.
For normal steel cents, condition is everything. A sharply struck, fully lustrous MS-65 example from San Francisco commands a strong premium over a corroded circulated piece — both are the same coin, but the collector market rewards preserved examples significantly.
