The 1943 Bronze Lincoln Cent is a rare U.S. error coin worth over $300,000. While most 1943 pennies were made of steel during World War II, a few were mistakenly struck in bronze, making them extremely rare.
Fewer than 20 are believed to exist, and they were later confirmed as genuine U.S. Mint errors. One famous example sold for over $200,000 after being found in everyday change.
Collectors identify real 1943 bronze pennies by weight and a simple magnet test—bronze coins are non-magnetic and heavier than steel versions.
This rare coin remains one of the most valuable discoveries in U.S. numismatic history.
