1951 Doubled Die Reverse DDR-012
Error
Description
Documented across an unusually comprehensive four-stage die progression, the 1951 Franklin half dollar DDR-012 presents medium spread on the lower bell and clapper of John R. Sinnock's Liberty Bell reverse design. VarietyVista documented this variety under UVC-287 and DMR-015, recording an unusually comprehensive four-stage die progression: Stage A at early die state (unconfirmed), Stage B at mid die state (unconfirmed), Stage C where the reverse has reached late die state with a die gouge appearing as a dot on the rear jaw line, and Stage D where both reverse and obverse surfaces have progressed to very late die state. The four-stage documentation — extending through VLDS — provides an exceptionally detailed record of this die's working life, tracking it from fresh surfaces through terminal deterioration. The die gouge dot appearing on the rear jaw line at Stage C offers a die-state-specific diagnostic: specimens showing this gouge but without the extreme wear of Stage D can be placed in the LDS range. The comments note RDV-001b, indicating this die utilized a specific reverse design variant — the same designation seen on several other 1951 Franklin half dollar DDRs — which can serve as an additional classification checkpoint. Philadelphia struck approximately 16.8 million Franklin halves in 1951, providing a moderate production base. Medium spread on the lower bell and clapper means the hub displacement is most visible on the lower portion of the bell's curvature and the hanging striker, where the rounded forms of these elements clearly reveal the secondary impression as a displaced shadow or thickened outline under moderate magnification. Collectors should examine the lower bell curve and clapper under 10-15x magnification, and can use the jaw line die gouge to determine die state placement within the documented progression.
