2005 (S) Proof Minnesota State Quarter - Doubled Die Reverse DDR-012

Description

Strong spread above a rock design element characterizes DDR-012 of a 2005-S clad proof State Quarter. Three die stages have been documented: Stage A showing Early Die State (EDS) on both reverse and obverse, Stage B at Mid Die State (MDS, unconfirmed), and Stage C at Late Die State (LDS, unconfirmed). This multi-stage documentation tracks the die's progressive wear from its initial sharp impressions through intermediate deterioration to its final worn condition. Die markers UVC-1883 and DMR-014 identify the die, and the VarietyVista attribution team cataloged this variety. San Francisco produced clad proof quarters for collectors as part of the 2005 State Quarter program, which featured five new reverse designs that year. The strong spread above the rock means the doubling should be visible without extreme magnification — strong indicates a clearly separated secondary image. On proof coinage, the superior strike quality and mirror-like surfaces make even moderate doubling easier to detect. The three die states provide collectors with a progression to pursue, as EDS specimens typically show the sharpest doubling detail while LDS examples may show the doubling overlaid with die deterioration effects.
