1951-S Doubled Die Reverse DDR-008
Error
Description
Cataloged as DDR-008 for the 1951-S Franklin Half Dollar, this variety exhibits medium spread on the lower bell and clapper of the Liberty Bell — the defining reverse element of John R. Sinnock's design. The "lower bell" refers to the bottom curvature of the bell's body while the "clapper" designates the internal striking mechanism visible through the bell's mouth. Medium spread on these sculptural elements produces visible displacement along the curved contours rather than flat lettering, requiring the examiner to trace secondary contour lines following the bell's profile. The reverse die variety is classified as RDV-001b (Reverse Die Variety 001b), identifying a specific reverse hub variant. Die markers UVC-285 and DMR-015 confirm the working die across three states: Stage A in Early Die State (unconfirmed), Stage B in Mid Die State (unconfirmed), and Stage C where both reverse and obverse reach Late Die State — the only confirmed stage. The 1951-S Franklin Half Dollar was struck at the San Francisco Mint in 90% silver at 12.5 grams. Examine the lower bell curvature and clapper under 7x magnification for medium displacement along the sculptural contours.
