1970 Doubled Die Obverse WDDO-020

Description

Listed as 1970 1¢ WDDO-020, this Philadelphia Mint doubled die obverse contributes another documented die to the extensive catalog of hub doubling varieties known on the 1970 Lincoln Memorial cent. No cross-references have been identified beyond the Wexler attribution system, meaning this variety has not been independently cataloged by CONECA or other organizations — a common situation for the more subtle DDO varieties where doubling strength may fall below the threshold some attributors use for inclusion. The absence of a cross-reference does not diminish the variety's validity; it simply reflects the practical reality that different organizations apply different criteria when evaluating which varieties merit formal listing. Philadelphia Mint production of Lincoln cents in 1970 was substantial, and the number of doubled die varieties identified across that single date-and-mintmark combination ranks among the highest in the entire Memorial cent series. WDDO-020's position in the numbering sequence places it among the later discoveries, where increasingly refined examination techniques and growing collector awareness of 1970-P DDOs prompted searches that uncovered progressively subtler varieties. Cherry-pickers hunting this variety should employ strong magnification and directional lighting to reveal the doubling characteristics that distinguish WDDO-020 from its neighboring catalog entries.
