1971-S WHR WHR-001

Description

Designated as the primary doubled working hub reverse for the 1971-S Proof Silver Eisenhower dollar, WHR-001 documents a hub doubling event that occurred at the working hub level rather than during die-to-coin transfer. The distinction between a doubled working hub and a doubled die is significant in numismatic variety classification — a doubled working hub produces the same doubling characteristics on every working die created from that hub, potentially generating a large population of affected coins, while a doubled die affects only the single working die that received the misaligned hub impression. Frank Gasparro designed the reverse of the Eisenhower dollar, featuring an eagle landing on the lunar surface with the Earth visible above — an adaptation of the Apollo 11 mission patch that connected the coin to the 1969 moon landing. The 1971-S proof silver Eisenhower dollar was struck at San Francisco with a composition of 40% silver and 60% copper in a special collector edition, with a mintage of approximately 6.87 million pieces. Cross-referenced as CONECA 1-R-I, this variety carries formal recognition from the Combined Organizations of Numismatic Error Collectors of America, the premier attribution organization for die varieties and minting errors. VarietyVista documented this variety under the WHR classification system. The working hub reverse doubling on the Eisenhower dollar's lunar landing design would affect elements of the eagle, moon surface, and Earth imagery — features whose organic contours and fine detail lines provide sensitive indicators of hub displacement. Collectors should examine the reverse design elements under 15-20x magnification, paying particular attention to the eagle's wing feathers and the lunar surface texture where the doubled working hub impression would produce thickened or displaced design features across all dies produced from the affected hub.
