1970 Lincoln Memorial Cent - Doubled Die Obverse WDDO-026

Description

WDDO-026 is a doubled die obverse on the 1970 Lincoln Memorial cent. No cross-references have been identified beyond the Wexler attribution system. The proliferation of doubled die varieties on 1970-P cents stems from the die manufacturing process in use during this era: working dies were created through multiple applications of a hub under hydraulic pressure, and each application cycle introduced the possibility of slight rotational or translational displacement. When that displacement exceeded a threshold visible under magnification, the resulting die qualified as a doubled die variety. With WDDO-026 occupying a position deep into the catalog, collectors can infer that this variety was likely identified through systematic searching after the major 1970-P doubled dies had already been well established in the numismatic literature. The variety collecting community's sustained interest in 1970 Philadelphia cents has ensured that even minor hub doubling has been documented, creating a comprehensive record of the die production variability that characterized this year's output. Cherry-pickers should examine IN GOD WE TRUST, LIBERTY, and the date numerals as primary zones where hub doubling manifests most visibly, using magnification and directional lighting to separate genuine doubling from die deterioration effects.
