Most people know that 1943 Lincoln cents were made from steel because copper was needed for the war effort. But a few rare experimental bronze cents were also made that year – and they’re worth a small fortune today.
These coins weren’t minting mistakes like the famous 1943 bronze error pennies, but intentional experiments done by the U.S. Mint to test new metal mixtures. Even though they were trials, they’re still extremely rare and valuable.
What Are the 1943 Experimental Bronze Cents?
In 1943, the U.S. Mint tested a few new bronze alloy combinations for making pennies. These experimental coins were different from both the regular steel pennies and the rare bronze error pennies struck by accident that same year.
One known experimental cent was made with:
- 91.7% copper
- 7.5% zinc
- 0.8% silver
Because of the unusual mix of metals, these coins look different in color and may have weaker details, since the new alloy didn’t strike the coin design as well.
How to Tell If You Have an Experimental Coin
Experts can tell the difference between an experimental bronze cent and the 1943 bronze error by examining:
- The metal’s color
- The strength and sharpness of the design
- The weight and composition
These experimental pieces may appear a bit duller and less defined compared to regular bronze or copper coins.
Because they were test pieces, most were not released into circulation. Some are now displayed in museums. One such coin is kept in the Edward C. Rochette Money Museum in Colorado Springs.
What Are They Worth?
If you ever come across one of these experimental 1943 bronze cents, don’t ignore it! These coins are extremely rare and can fetch at least $150,000, depending on their condition and history.
Since very few exist, coin collectors and museums are always interested in verified examples. If you think you have one, it’s important to get it professionally graded by a trusted coin grading service.
The 1943 experimental bronze cents are unique pieces of U.S. coin history. While not mint errors, they are rare test coins that never made it into full production. Their unusual composition, scarcity, and story make them highly valuable—often worth over $150,000. If you find one, you may be holding a piece of history that could change your life.
FAQ’s
What are 1943 experimental bronze cents?
These are rare test coins made by the U.S. Mint in 1943 using unique bronze alloy mixtures. They were created for experimentation, not as mint errors.
How are experimental bronze cents different from 1943 bronze error pennies?
Experimental cents were made on purpose with new metal mixes. Error pennies were struck on leftover bronze planchets by mistake.
What metals were used in one of the experimental 1943 cents?
One example was made with 91.7% copper, 7.5% zinc, and 0.8% silver. It is now displayed in the Edward C. Rochette Money Museum.
How much is a 1943 experimental bronze cent worth?
A verified coin can be worth around $150,000 or more, depending on its condition and rarity.
How can I tell if I have an experimental bronze cent?
Experts check the metal’s color, strike quality, and composition. If you think you have one, get it graded by a professional coin service.
