1964 Doubled Die Reverse WDDR-010

Description

Tenth cataloged doubled die reverse on the 1964 Proof Roosevelt Silver Dime, WDDR-010 extends the substantial documentation of hub doubling varieties from the final year of silver proof dime production at the Philadelphia Mint. The Wexler Team attributed this variety, assigning the designation Wexler Variety ID 1964 10c Pr WDDR-010, with no additional cross-references in other attribution frameworks. Philadelphia's record 3,950,762 proof sets in 1964 consumed numerous die pairs, and the multi-impression hubbing process used to create proof-quality dies generated frequent opportunities for slight displacement between successive hub impressions. Roosevelt Dime proof reverses from 1964 are a prolific source of doubled dies because Sinnock's reverse design — torch, branches, lettering, and ribbon — contains fine detail across the entire die face where even minor hub shift registers visibly. The significance of 1964 as the last 90% silver dime year adds collector interest beyond the variety itself: these coins contain approximately 0.0723 troy ounces of silver, giving them intrinsic metal value that underpins numismatic demand. Collectors examining 1964 proof dimes should note that the large proof production figure means examples are obtainable, though identifying specific WDDR numbers requires careful comparison against published die marker photographs.
