1960 Proof Doubled Die Obverse WDDO-013
ErrorDescription
At the extreme end of detectable hub doubling, WDDO-013 on the 1960 Lincoln Memorial Cent Proof Large Date displays an extremely close spread towards the rim on the letters of LIBERTY. The rimward displacement indicates the secondary hub impression shifted very slightly outward from the coin's center, and on this variety the separation between primary and secondary images is so narrow that it challenges even practiced attributors working under high magnification. Detection typically requires at least 16x power and meticulous comparison of each letter's outer edge against known normal specimens, looking for the faint secondary outline that defines the spread. The Large Date designation places this die in the earlier proof production phase at Philadelphia, before the mid-year hub transition to the Small Date design. No significant die markers were identified on either the obverse or reverse, eliminating the shortcut that many attributors rely on when confirming close-spread varieties. The proof format — with its polished dies and specially prepared planchets — actually provides a modest advantage here, as the mirror-like fields heighten contrast at the letter edges where the displaced secondary impression is most likely to be resolved. Cataloged by the Wexler Team as 1960 1¢ Pr WDDO-013, the variety carries no other known cross-references and represents a cataloging boundary case where genuine but minimal hub doubling has been verified.
