2006-D Doubled Die Reverse WDDR-001

Description

Documented across three major attribution systems with the primary WDDR-001 designation, the 2006-D doubled die reverse on the Denver Mint Lincoln Memorial cent is thoroughly cataloged. CONECA lists this as 6-R-VIII, Coppercoins as 2006D-1DR-006, and the Wexler system as 2006-D WDDR-001. The CONECA Class VIII classification identifies tilted hub doubling, where the hub was angled during impression into the working die. Struck near the end of the Lincoln Memorial cent era, which concluded in 2008 when the design gave way to the four Lincoln Bicentennial reverses, the 2006-D represents one of the later Memorial reverse doubled dies to enter the catalog. Die hubbing misalignment produced visible doubling on Frank Gasparro's architectural reverse design, whose columns, steps, and lettering provide multiple surfaces where tilted hub displacement becomes detectable. The triple attribution across Wexler, CONECA, and Coppercoins confirms this as a well-documented variety, and its WDDR-001 status as the primary doubled die reverse for the date makes it the first variety specialists seek when examining 2006-D Memorial cents.
