Repunched Date Up until the early 20th century, most U.S. coins had dates hand-punched directly into working dies. A repunched date is simply the result of one date being punched into a die over another date of the same year. It was the result of the punch moving out of alignment during the multiple blows that it took to impress the date into the die.

Repunched Mintmark Up until the late 20th century, U.S. coins had mintmarks hand-punched directly into working dies. A repunched mintmark is simply the result of the punch moving out of alignment during the multiple blows that it took to impress the mintmark into the die. This resulted in multiple occurrances of the same mintmark on coins at various angles to each other or even upside-down. In 1985, the mintmark was added to the hub for proof coinage. In 1990, the mintmark was added to the hub for circulating coinage.
