1964 Proof Doubled Die Obverse WDDO-011

Description

Bearing the eleventh Wexler doubled die obverse designation in the Proof-prefixed sequence for the 1964 Lincoln cent, this variety is one of the many proof hub doubling entries generated during a year of extraordinary Mint output. The Philadelphia Mint struck 3,950,762 proof cents in 1964, with each proof die pair serving roughly 3,000 impressions before being retired to maintain the flawless surface quality demanded of proof coinage. The dies themselves were created through the same hubbing process used for business strike dies, pressing the master hub into a softened die blank multiple times to fully transfer the design. Any rotational or translational shift between these sequential impressions would produce a doubled die, and across the many die pairs needed for the 1964 proof run, multiple misalignments inevitably occurred. The result is a deep catalog of proof DDO varieties for this date. No specific doubling description, die markers, cross-references, or expert attributions have been published for this variety beyond the Wexler catalog listing. Collectors should note that proof doubled dies from 1964 occupy a distinctive collecting niche: they combine the mirror-finish aesthetic of proof coinage with the research-driven pursuit of die variety identification. Attribution requires careful comparison against Wexler reference photographs at 10x or higher magnification. Struck on a polished 3.11-gram, 19mm bronze planchet of 95% copper and 5% tin-zinc.
