2006 Doubled Die Obverse WDDO-037

Description

Thirty-seventh cataloged doubled die obverse for the 2006 Lincoln Memorial Cent in the Wexler system, WDDO-037 exhibits light extra thickness on LIBERTY with distinctive notches on the upper left portions of the letters ERTY. The "notches on the upper left ERTY" diagnostic describes a specific doubling signature where the secondary hub impression displaced design detail slightly to the upper left, creating small protrusions or extensions on the upper-left edges of these letters while leaving their opposite sides unaffected. This asymmetric notching pattern is a reliable diagnostic because it indicates both the direction and relative magnitude of the hub displacement. Die markers are documented for both sides: the obverse carries a small die gouge above the B in LIBERTY and die scratches running SSW/NNE to the right of the lips, while the reverse shows die pitting in the tenth Memorial bay — all details that serve as unique die-pair identifiers. No cross-references to other attribution systems are currently known. The 2006 Lincoln Memorial Cent was produced at Philadelphia during the penultimate year before the 2009 bicentennial reverse program temporarily replaced the Memorial design. Thirty-seven cataloged doubled die obverses for the date demonstrates the prolific variety output that characterized late-era Memorial Cent production, when high-speed automated hubbing processes generated subtle but detectable doubling across numerous die pairs. The Memorial Cent's fifty-year production span (1959-2008) generated thousands of documented doubled die varieties, making it one of the most thoroughly researched U.S. coin designs in numismatic history.
