Blunder Date

Definition: A date that has been obviously entered wrong onto a master or working die.

The date was inadvertently punched into the 1853 half dime working die in an inverted position. It was then correctly positioned and repunched. However,  some of the first punched digits in the date remained on the die.

The oddity on this half dime can also be considered a repunched date since the error was corrected.
