Trama

Can You Spot The Errors? This coin looks a bit mangled, as if a car ran over it. It's really a copper cent struck on a silver dime. And no, that doesn't make it worth a nickel. The excess of metal at the top of the Lincoln cent is called a cud. It is caused when a piece breaks from the die face and leaving a hole into which the metal flows as the coin is struck.
