1976-S Doubled Die Reverse DDR-001

Description

Holding the primary DDR designation for the 1976-S Bicentennial Eisenhower dollar clad proof, DDR-001 exhibits light spread on the inscriptions UNITED and ONE DOLLAR on the special reverse designed by Dennis R. Williams. The Bicentennial reverse, featuring the Liberty Bell superimposed on the Moon, replaced the standard Eisenhower reverse for coins dated 1776-1976, and the combination of detailed lettering and the bell's complex surface textures provides diagnostic surfaces where hub doubling is detectable. VarietyVista assigned identifiers UVC-078 and DMR-005, tracking three die stages: Stage A where both reverse and obverse surfaces exhibit early die state characteristics, Stage B at mid die state (unconfirmed), and Stage C at late die state (unconfirmed). The EDS confirmation for Stage A indicates specimens with fresh, unworn die detail have been documented. Notably, this is a clad-nickel proof (CN Proof) struck at the San Francisco Mint, where proof production employed polished dies and specially prepared planchets to create mirror-finish coins with frosted devices. The comments note ODV-008 and RDV-004, identifying the specific obverse and reverse design variants used for this die pair — classifications that help researchers track which master die lineages were active during the Bicentennial proof program. Light spread on UNITED and ONE DOLLAR means the doubling is detectable but does not produce dramatic visual separation, requiring at least 10-15x magnification with careful comparison against the primary letter impressions. San Francisco produced both copper-nickel clad and 40% silver Bicentennial proofs across 1975-76 production, and the CN Proof notation confirms this variety belongs to the base-metal clad issue rather than the silver collector edition.
