1960-D Repunched Mintmark RPM-018

Description

Among the most extensively staged repunched mintmark varieties in the 1960-D Large Date series, RPM-018 spans nine die stages across two reverse die pairings. Cataloged by VarietyVista as UVC-657/DMR-025 and UVC-658/DMR-026, this die's exceptionally long service life provides a detailed case study in die deterioration under high-volume production. Under the first reverse (UVC-657/DMR-025): Stage A: EDS (unconfirmed). Stage B (EMDS): two parallel NW-SE die scratches under T of LIBERTY, minute die chip on right cornice at MDS. Stage C (MDS): obverse is MDS, die break on column 12 at LMDS, depression at right eave. Stage D (MDS): die break at right eave at LMDS. Stage E (MDS): die break above right cornice at LDS. After the reverse die change (UVC-658/DMR-026): Stage F (LMDS): vertical die scratch between 1 and 9 of date, reverse die changed at MDS. Stage G (LMDS): die chip on right cornice, die crack on column 12. Stage H (LDS): NE-SW die scratches on obverse, die crack on forehead, die break on right cornice, die chips on column 12. Stage I (MDS): E-W die scratches on both obverse and reverse, die chips on column 1. The nine-stage span across two reverse pairings demonstrates that this obverse die consumed two complete reverse dies during its production run.
