Repunched Mint marks are a form of die variety resulting from the hands-on techniques used in die production from U.S. Mint's origins in 1792 through the late 20th century. Until 1990, all Mint marks were punched by hand into individual working dies, whose numbers could totals thousands over the course of a year. On some dies, the first attempt at punching a Mint mark may have been insufficient to form a fully shaped Mint mark. If the Mint technician failed to properly position the punch the second, overlapping Mint marks could be created on a die, with both Mint marks visible.
Technological changes introduced in 1990 and refined in the years since eliminated the variability in Mint mark position, icnluding making repunched Mint marks impossible.
