1970-S Proof Doubled Die Reverse WDDR-006

Description

Sixth in the Wexler doubled die reverse catalog for the 1970-S Proof Lincoln Memorial cent, WDDR-006 presents a Large Date variety with hub doubling spread distributed across multiple reverse design elements — the designer's initials, UNITED STATES OF AMERICA, E PLURIBUS UNUM, ONE CENT, and the left side of the Lincoln Memorial. This breadth of affected elements indicates a relatively uniform translational shift between hub impressions, displacing the entire reverse design laterally rather than producing the localized distortions characteristic of rotational or pivot doubling. The absence of significant die markers noted in the attribution record suggests this die entered and exited service without developing the scratches, gouges, or cracks that often accumulate during a die's working life — possibly indicating a relatively short production run before the die was retired or replaced. For attribution purposes, the wide distribution of doubling across multiple inscriptions provides numerous verification points: collectors can cross-check the spread on USA against the spread on EPU, ONE CENT, and the Memorial structure to confirm consistency with a single hub displacement event. On proof specimens, where the cameo contrast between frosted devices and mirrored fields reaches its peak in early die states, the doubled die evidence may appear as a subtle shelf or secondary outline along the edges of affected letters and design elements. WDDR-006 joins WDDR-005 in documenting the reality that San Francisco's proof die preparation was subject to the same hubbing misalignment risks as any other Mint facility, and that the 1970-S proof issue generated a meaningful roster of doubled die varieties across both obverse and reverse surfaces.
