The 1943 Steel Wheat Penny is unique in American coinage—made of zinc-coated steel due to wartime copper shortages.
Most are worth mere cents even today, but a small handful of ultra-rare variants and errors have fetched millions at auction.
Curious about what might be hiding in your coin collection? Here’s your 2025 guide to the 7 most valuable 1943 Steel Wheat Pennies, their defining traits, and how to spot potential million-dollar pieces.
Why Some 1943 Steel Wheat Pennies Soar in Value
Most 1943 steel penny hold only nominal value, but a rare few break the mold:
- Off-metal errors, especially those struck on copper or tin planchets instead of steel.
- Mint errors like repunched mintmarks (RPM) or doubled die obverse (DDO) varieties.
- Exceptional condition (Mint State)—few survive uncirculated due to rust and wear.
- Extreme rarity—some variants have only one or two known survivors.

Spotlight on Top Tier Rarities
1. 1943 Copper Cents
The rarest of them all—mistakes using bronze instead of steel. The Philadelphia example sold for over $1.7 million. Striking beauty and unimaginable rarity make it a numismatic legend.
2. 1943 Tin Penny
Only one known, composed mostly of tin with high collector intrigue. Value is speculative but undeniably astronomical.
3. 1944 Steel Penny (S)
A transition error struck on leftover steel planchets. One MS66 sold for $408,000, and top-grade pieces have potential to break the million-dollar ceiling.
4. Mint Errors: RPM & DDO
More accessible than off-metal rarities, but still valuable. Examples like the 1943-D/D repunched mintmark can fetch thousands, while a DDO in MS66 can reach around $1,500.
How to Identify a High-Value 1943 Penny
- Use a magnet – steel cents stick, but copper or tin errors do not.
- Weigh the coin – steel coins weigh ~2.7 g; copper ones are ~3.11 g.
- Inspect the mintmark – doubling or mis-punching (e.g. “D/D”) signals RPM.
- Check surface and detail – rust-free, sharp strike and lustrous fields point to Mint State.
- Seek professional grading – Authentication and slab grading are essential for high-value pieces.
While most 1943 Steel Wheat Pennies are common—and worth only cents—keep an eye out. A rare off-metal copper or tin variant, or even a high-grade mint error, could be worth six or seven figures.
If you find a well-preserved, unusual 1943 penny, get it authenticated—it just might be your lifetime discovery.
FAQs
Only ultra-rare off-metal errors (like copper or tin strikes) have crossed the million-dollar mark. Regular steel pennies remain low-value.
Use a magnet (steel sticks, copper does not) and a precision scale to compare weight (~3.11 g for copper, ~2.7 g for steel).
While not in the millions, mint errors can fetch thousands—especially in high Mint State (MS) grades.
