1970 Doubled Die Obverse DDO-006

Description

Shifting the doubling location to the base of the date, DDO-006 on the 1970 Lincoln Memorial cent shows a medium spread manifesting as an extra bar below the 70 of the date. Cataloged under die markers UVC-2238 and DMR-007, the downward displacement distinguishes it from the over-the-7 doubling seen on DDO-002, DDO-003, and DDO-004. The direction of the extra bar — below rather than above the date digits — indicates a specific vector of hub misalignment during die sinking. This directionality is central to doubled die classification, where spread geometry helps researchers reconstruct the mechanical event that produced the doubling. Medium-strength spread on the 70 provides enough visual evidence for confident attribution at standard magnification. The distinguishing feature versus die deterioration is definition: genuine hub doubling produces clean, parallel extra bars with distinct boundaries, while deterioration creates diffuse metal displacement without sharp edges.
