1952-S Repunched Mintmark RPM-001

Description

Cataloged by VarietyVista as RPM-001 with universal variety code UVC-433 and die marriage record DMR-002, this 1952 San Francisco Lincoln wheat cent carries the primary RPM designation for the date-mint combination. Three die stages document the progressive deterioration of this die pair. Stage A in early-to-mid die state shows concentric circle lathe marks on Lincoln's head and a patch of parallel die scratches beneath the N of CENT, both remnants of die preparation. By Stage B at mid-die state, a die clash appears at Lincoln's throat on the obverse and die scratches running north-northeast become visible across the reverse. Stage C in late die state has unconfirmed markers. The lathe marks in Stage A represent evidence of the circular polishing motion used during die finishing at the San Francisco Mint. As the number-one RPM listing for the 1952-S cent, this variety occupies a prominent position among wheat cent repunched mintmark varieties, and the documented stage progression gives collectors a reliable framework for dating specimens within the die's production life.
