2008 (P) New Mexico State Quarter - Doubled Die Reverse WDDR-008

Description

WDDR-008, a doubled die reverse for the 2008 Philadelphia Mint New Mexico State Quarter, illustrates how the high-speed production demands of the State Quarter program created conditions favorable for die variety generation. Each working die at the Philadelphia Mint could strike tens of thousands of quarters before requiring replacement, and each of those dies was prepared through a multi-step hubbing process where alignment precision was critical but imperfect. When the hub shifted between impressions during die sinking, the resulting doubled die transferred its overlapping design to every coin produced from that die until it was retired. The New Mexico reverse's state outline provides geographic contour lines where doubling may manifest as a shadow or thickened border. Cross-referenced as Wexler Variety ID 2008-P 25¢ NM WDDR-008, this variety requires comparison against neighboring WDDR numbers to confirm attribution.
