1942-D Repunched Mintmark RPM-010

Description

Ten repunched mintmark varieties documented for the 1942-D Mercury Dime speak to the enormous die production required as the United States ramped up wartime coinage output. RPM-010 displays a D/D East displacement, where the Denver mintmark was initially punched slightly eastward of its intended position before receiving a corrective final blow. Denver struck 60,740,000 dimes in 1942, the final year of the standard silver alloy composition before wartime modifications affected other denominations (though dimes retained their 90% silver content throughout the war, unlike nickels which switched to a silver-manganese-copper alloy). The eastward displacement direction on RPM-010 aligns with the most commonly documented directional tendency across Mercury Dime RPMs from Denver, consistent with ergonomic factors in the hand-punching process. Adolph A. Weinman's Mercury Dime obverse — properly titled the Winged Liberty Head — depicts Liberty wearing a winged Phrygian cap that was frequently misidentified as the Roman god Mercury, giving the coin its enduring popular name. The mintmark location on the reverse, positioned at the base of the fasces near the lower left, was the site where each working die received its individual D punch. With ten RPMs documented, the 1942-D date ranks among the more variety-rich Denver Mint Mercury Dimes, reflecting both the number of dies consumed during high-output wartime production and the dedication of researchers who have examined thousands of specimens under magnification. Mercury Dime RPM collecting offers an accessible entry point for beginning variety collectors, as many examples remain affordable in circulated grades.
