2006-D Doubled Die Reverse WDDR-007

Description

Seventh cataloged doubled die reverse for the 2006 Denver Lincoln Memorial Cent, WDDR-007 documents hub misalignment that produced visible doubling on what would prove to be one of the final production years for Frank Gasparro's iconic Memorial reverse design. The Wexler Team attributed this under ID 2006-D 1¢ WDDR-007, with no known cross-references in competing attribution systems such as CONECA or the Fivaz-Stanton Cherrypickers' Guide. Denver produced approximately 3.9 billion Lincoln Cents in 2006, a massive output that generated extensive variety populations across the doubled die, repunched mintmark, and die break categories. The Memorial reverse, entering its forty-eighth year of continuous use in 2006 with only two more years of production remaining before the 2009 bicentennial designs, had accumulated the most thoroughly documented variety catalog of any United States coin reverse design. Each WDDR number represents an independent die whose manufacture involved at least one hub impression misaligned sufficiently to produce identifiable doubling — and seven such dies documented for 2006-D alone illustrates the statistical regularity with which hub misalignment occurred across modern high-volume die production. Collectors screening 2006-D cents should examine the reverse inscriptions, Memorial columns, and steps under magnification, comparing suspicious features against the specific spread direction and affected design elements documented for each of the seven cataloged varieties. The absence of cross-references underscores the Wexler catalog's role as the primary documentation source for this variety.
