1951-S Doubled Die Reverse DDR-001

Description

Cataloged by VarietyVista, the 1951-S Franklin Half Dollar DDR-001 presents a medium spread on E PLURIBUS UNUM and the left eagle wing on John R. Sinnock's reverse design. The spread across both the national motto and an architectural element of the heraldic eagle provides multiple diagnostic checkpoints for attribution. Die markers UVC-050 and DMR-002 identify the working die, which has been documented across three die stages: Stage A tentatively in early die state (unconfirmed), Stage B tentatively in mid-die state (unconfirmed), and Stage C confirmed with both reverse and obverse in late die state. The comments note two reverse die varieties — RDV-001b and RDV-001a — indicating this die underwent observable changes during its service life. The Franklin Half Dollar series (1948-1963) features Sinnock's portrait of Benjamin Franklin on the obverse and the Liberty Bell on the reverse, struck in 90% silver at 12.5 grams. This San Francisco Mint regular strike carries the S mintmark. Examine E PLURIBUS UNUM and the contours of the left eagle wing under magnification for the medium-intensity spread that defines DDR-001.
