1942-S Repunched Mintmark RPM-001

Description

The primary repunched mint mark for the 1942-S Mercury Dime, RPM-001 displays a triple-punched S/S/S with both secondary impressions shifted to the west — a triple mint mark punch that records three distinct placement attempts during the die preparation process. The west-west direction indicates both re-punchings shifted in the same direction, creating a progressively layered effect at the western edge of the S. An important additional diagnostic identifies the mint mark style as MMS-003, known as the Trumpet Tail S — a distinctive punch variety where the lower terminal of the S flares outward in a trumpet-like shape, distinguishing it from other S mint mark punches used during this production period. Triple-punched mint marks are significantly scarcer than standard doubled mint marks, as they record an unusually persistent misalignment that required three attempts before achieving acceptable placement. The 1942-S Mercury Dime was struck at the San Francisco Mint in 90% silver during the early wartime years of Adolph A. Weinman's design. As RPM-001, this holds the top-ranked position for repunched mint marks on the date, and the combination of triple punching with the identifiable Trumpet Tail mint mark style creates a variety with both visual impact and numismatic documentation value for collectors focused on the mint mark attribution subspecialty.
