The over mint mark is created when a one date and mint mark is punched over another date, part of a date, or mint mark. These coins are generally restricted to the early minting process of coins dating before the turn of the century.

A die crack occurs when a die, after being subjected to immense pressure during the minting process, cracks, causing a small gap in the die. [3] If this damaged die continues to produce coins, the metal will fill into the crack, thus revealing a raised line of metal in the finished coin.
