Description
Documented by VarietyVista with an S/S South displacement, this 1971 San Francisco proof Washington Quarter carries a repunched S mintmark on a proof striking. Die markers: UVC-1229, DMR-010. Stage A: Obverse is EDS; die gouges down eagle's wings — EDS. Stage B: MDS (unconfirmed). Stage C: LDS (unconfirmed). The eagle's wing gouges at EDS provide early-state markers characteristic of die preparation artifacts. RPMs on proof coins are less common than on business strikes due to enhanced quality control at San Francisco. John Flanagan's design was struck as a proof in copper-nickel clad (5.67 g, 24.26 mm). The 1971-S proofs were included in annual proof sets, where mirror-like fields can make the southward RPM displacement more visible.
