1964 Proof Doubled Die Obverse WDDO-023

Description

Occupying the twenty-third position in the Proof-prefixed doubled die obverse sequence for the 1964 Lincoln cent, this variety is part of the expanding catalog of proof hub doubling discovered among the 3,950,762 proof cents struck at the Philadelphia Mint. The depth of the proof DDO catalog for this single date is a testament to the dedicated variety researchers who have systematically examined proof sets coin by coin, documenting each new doubled die with photographs and die marker analysis. Each variety number represents a unique die that experienced its own individual hubbing misalignment, creating a doubling pattern that differs from every other WDDO in the catalog even when the differences may appear minor to the untrained eye. No specific doubling description, die markers, cross-references, or expert attributions have been published for this variety beyond the Wexler catalog listing. Collectors should approach attribution methodically: first identify the design elements that appear doubled, then determine the direction of the spread, and finally compare these observations against reference photographs for the specific WDDO number under consideration. Working under a stereo microscope with fiber-optic illumination provides the clearest view of subtle proof doubling, as the adjustable lighting helps separate genuine doubled images from the optical reflections inherent in mirror proof surfaces. Struck on a polished 3.11-gram, 19mm bronze planchet of 95% copper and 5% tin-zinc.
