Imagine finding a simple penny in your pocket change — and discovering it’s worth over a million dollars. That’s exactly what happened to a few lucky people who came across the 1943 Copper Penny. During World War II, the U.S. Mint switched to steel pennies to save copper for the war effort. But by mistake, a few copper planchets (blank coin discs) were left behind and got struck with the 1943 design. These rare errors created one of the most legendary coins in American history.
Let’s explore how this accidental coin became one of the most valuable in the world, why collectors love it, and how to tell if you might have one.
Coin Name: 1943 Copper Lincoln Penny
1. Why Was the 1943 Penny Supposed to Be Steel?
In 1943, the United States was in the middle of World War II. Copper was needed for military equipment like bullets, wires, and communication devices. So, to help the war effort, the U.S. Mint decided to strike all pennies that year in zinc-coated steel instead of copper.
The steel pennies looked different — silver-gray instead of the usual brownish-red of copper. But something unexpected happened…
2. The Mistake: Copper Planchets Left Behind
Even though the mint had changed to steel planchets in 1943, a few leftover copper blanks from 1942 were mistakenly fed into the presses. These copper coins were struck with the 1943 design — creating a rare and valuable minting error.
Only an estimated 15 to 20 genuine 1943 copper pennies are known to exist today, making them one of the rarest U.S. coins.
3. How Much Is a 1943 Copper Penny Worth?
Due to its extreme rarity, collectors are willing to pay huge amounts. Here are some notable auction results:
- In 2010, a 1943 copper penny sold for $1.7 million.
- In 2019, another one sold for over $200,000.
Prices vary depending on the coin’s condition and which mint struck it (Philadelphia, Denver, or San Francisco).
4. How to Identify a Real 1943 Copper Penny
Here are some tips to spot a genuine one:
- Use a magnet: Steel pennies stick to magnets, but copper ones don’t.
- Check the weight: Copper pennies weigh about 3.11 grams, steel ones weigh around 2.7 grams.
- Color: A 1943 penny that is brown or reddish may be copper.
- Get the coin authenticated by experts like PCGS or NGC before assuming it’s real.
Beware! Many fakes exist — some are steel pennies coated in copper or altered 1948 coins with the “8” reshaped to look like a “3.”
