1940-S Doubled Die Reverse DDR-007

Description

Cataloged by VarietyVista with Universal Variety Code UVC-1470 and Die Marriage Record DMR-023, the 1940-S Lincoln Wheat Cent DDR-007 displays extra thickness on E PLURIBUS UNUM, the right wheat ear and stem, and light spread on the upper left wheat ear. The distribution of doubling across multiple reverse design elements — inscription, right stalk, and left stalk — indicates a hub displacement that affected a broad zone of the reverse die face rather than a localized area. Die stage documentation tracks three phases: Stage A at Early Die State (unconfirmed), Stage B where both the reverse and obverse reach Mid Die State, and Stage C where both advance to Late Die State. The MDS-to-LDS progression on both sides simultaneously suggests the obverse and reverse dies were wearing at comparable rates, a balanced die wear pattern that contrasts with some die marriages where one die deteriorates significantly faster than its partner. The 1940-S Lincoln Wheat Cent was struck at the San Francisco Mint in the standard bronze alloy (95% copper, 5% tin and zinc) at 3.11 grams and 19 mm diameter. San Francisco's 1940 cent production of 112,940,000 pieces was substantial, and the seventh cataloged DDR reflects the variety-producing potential of high-volume cent production. Victor David Brenner's wheat ears reverse, with its two stalks flanking the central inscriptions, provides the paired design elements where the doubling manifests — the spread visible on both stalks, though with different intensities, confirms the radial nature of the hub displacement event that created this variety.
