A Penny Worth Over Half a Million?
Yes, you read that right! 
In 2023, a 1943 Copper Lincoln Cent sold for an astonishing $504,000, making it one of the most legendary coins in American history.
During World War II, the U.S. Mint switched from copper to steel to conserve materials for the war. But a few copper blanks slipped through — creating one of the most valuable minting mistakes ever made.
With fewer than 15 known worldwide, this coin is the “Holy Grail” of U.S. pennies — and one could still be hiding in a jar, drawer, or coin roll near you!
