1970 Doubled Die Obverse WDDO-023

Description

Numbered as 1970 1¢ WDDO-023, this Philadelphia Mint doubled die obverse extends the Wexler catalog into the upper twenties for the prolific 1970-P Lincoln Memorial cent date. No cross-references have been identified in other attribution systems, placing documentation responsibility solely within the Wexler framework. The 1970 Philadelphia date occupies a distinctive position in Lincoln cent variety collecting: it falls within a transitional period for U.S. Mint die production, when the multiple-hubbing process used to create working dies was generating an exceptional volume of doubled die varieties across all denominations. Each WDDO number represents a physically distinct working die that received its hub impressions with detectable misalignment, and the high Wexler numbers for this date testify to the thoroughness with which variety researchers have examined 1970-P cents. WDDO-023's position late in the sequence suggests it was identified after the more dramatic doubled dies from this date had already been cataloged and publicized. Collectors cherry-picking 1970 Philadelphia cents for doubled dies benefit from the sheer number of known varieties — with more than two dozen WDDOs documented, the probability of encountering at least one attributable variety in a given quantity of coins is meaningfully higher than for dates with only a handful of known dies.
