1970 (D) Lincoln Memorial Cent - Doubled Die Obverse WDDO-009

Description

Ninth in John Wexler's numbered sequence of 1970-D Lincoln cent doubled die obverses, WDDO-009 carries the full designation 1970-D 1¢ WDDO-009 with no known cross-references to other published attribution services. Hub doubling occurs when a working die receives two or more impressions from the hub during the die-making process, with slight misalignment between impressions leaving ghost images of design elements on the finished die. On 1970-D cents, the horizontal crossbar of the 7 in the date serves as the primary diagnostic zone because even minimal vertical displacement between hub impressions produces a visible extra bar or thickening at this feature. Collectors examining raw 1970-D cents should use 10x to 20x magnification focused on the date numerals, LIBERTY, and IN GOD WE TRUST — the three areas where rotational or vertical doubling most commonly manifests. Because no cross-references exist, attribution relies entirely on matching die markers documented in Wexler's research files, making access to his published photographs or die marker notes essential for definitive confirmation.
