If you’ve ever picked up a penny and wondered if it’s worth more than just one cent, you’re not alone. Some coins—especially ones with rare errors or unusual metals—can fetch incredible prices. The 1943 steel penny is one of the most famous examples. But did you know that the rarest version, the 1943 copper penny, could be worth as much as $1.4 million?
Let’s cut into what makes this coin special, how to spot one, and what you should do if you think you have a valuable penny on your hands.
History
During World War II, copper was needed for ammunition and other military supplies. To conserve this metal, the U.S. Mint switched from copper to zinc-coated steel for the penny in 1943. Over a billion of these silver-gray steel pennies were made.
But here’s where it gets interesting: a few copper blanks from 1942 were accidentally used in 1943. These copper 1943 pennies are extremely rare, and that’s where the big money comes in.

Importance
What makes the 1943 penny so sought-after?
- Material Shift: It’s the only year U.S. pennies were made from steel.
- Mint Error: A handful of copper pennies slipped through by accident.
- Historical Context: These coins are relics from a time of global conflict and change.
- Collectible Value: The copper version is one of the rarest and most valuable U.S. coins.
Identify
So, how do you know if the 1943 penny you found in a drawer or piggy bank is one of the valuable ones? Follow these steps.
1. Try the Magnet Test
Hold a magnet next to your 1943 penny. If it sticks, it’s a steel penny and not the rare one. If it doesn’t stick, you might have something special.
2. Weigh It
Use a digital scale. A steel penny weighs 2.7 grams. A copper penny weighs about 3.11 grams. A penny that weighs more than 3 grams and doesn’t stick to a magnet should be examined by a pro.
3. Check the Color
Steel pennies look silver or gray. Copper pennies have the familiar reddish-brown look. If your penny looks like a regular old copper one but says 1943, get it checked.
4. Look for Mint Marks
Look below the year on the penny.
- No letter = Philadelphia
- D = Denver
- S = San Francisco
Any 1943 copper penny from any mint is rare, but mint marks can impact collector interest.
Value
A real 1943 copper penny is worth a fortune. Prices depend on:
- Condition (Uncirculated coins sell for much more)
- Grading (Mint State coins rated MS65+ fetch the most)
- Authenticity
In 2010, one such coin sold for $1.4 million at auction. Even coins in lesser condition can still be worth hundreds of thousands.
Appraise
Think you might have one? Here’s what to do next.
1. Visit a Coin Expert
A professional numismatist can examine the penny and give an initial opinion. Look for dealers certified by the American Numismatic Association (ANA).
2. Use a Grading Service
Services like PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Corporation) provide official grading, which boosts credibility and value.
3. Consider Selling at Auction
If the penny is the real deal, auction houses like Heritage Auctions or Stack’s Bowers are great places to get top dollar.
4. Sell Online (with Caution)
You can use sites like eBay, but ensure your coin is graded and certified. Photos and proof of grading are crucial to avoid scams or low offers.
Investing
Coins aren’t just collectibles—they can be long-term investments.
- Rarity = Value: The fewer there are, the more they’re worth.
- Condition Matters: Clean, uncirculated, graded coins always sell for more.
- Watch Trends: Coin prices rise and fall based on demand, rarity, and market conditions.
- Diversify: Like any investment, don’t put all your funds into one coin type.
