Why Was the 1943 Steel Penny Made?
In 1943, the U.S. was deeply involved in World War II, and copper was in high demand for military supplies like bullets and shell casings. To conserve copper, the U.S. Mint switched to steel pennies coated in zinc for that year. However, these steel coins had their own issues—they rusted easily and were often mistaken for dimes due to their silver appearance.
By 1944, the Mint returned to making pennies from copper, but the 1943 steel penny remained a distinctive piece of numismatic history. Today, these coins are highly sought after, especially those with minting errors.
How to Identify a 1943 Steel Penny Without a Mint Mark
If you have a 1943 steel penny, here’s how to check if it’s an error coin and determine its potential value:
- Check the Date and Mint Mark – Look at the front (obverse) of the penny. If there’s no mint mark under the year, it was made in Philadelphia.
- Magnet Test – A genuine steel penny will stick to a magnet due to its iron content. If it doesn’t, you may have a rare bronze error coin.
- Look at the Color – A real steel penny should have a silver-gray appearance. If it looks copper, it may be an error coin or a fake.
- Weigh the Coin – A proper 1943 steel penny weighs 2.7 grams, while an extremely rare 1943 copper penny weighs 3.11 grams.
