2016 Doubled Die Reverse WDDR-010

Description

Reaching the tenth position in the Cumberland Gap Quarter DDR census, WDDR-010 (Wexler reference 2016-P 25c KY WDDR-010) demonstrates that the Philadelphia Mint's 2016 die population for this design generated hub doubling events at a statistically notable rate. Each DDR number represents a distinct reverse working die that received a misaligned secondary hub impression during manufacture, and ten such events within a single design issue confirms both the high die consumption rate for ATB quarter production and the vigilance of attributors who examine this modern series. The Cumberland Gap reverse, with Daniel Boone surveying the westward passage through the Appalachian Mountains, includes fine landscape detail — distant ridgelines, foreground rock textures, tree canopy — that provides numerous surfaces where subtle doubling can manifest as displaced contours or thickened edges. No additional cross-references beyond the Wexler designation are known for WDDR-010. Struck on copper-nickel clad planchets at the standard quarter weight of 5.67 grams, these coins were released into general circulation and can be found through systematic roll searching with appropriate magnification. Collectors building a comprehensive Cumberland Gap DDR set should note that attributing WDDR-010 among its neighbors requires precise characterization of the doubled area, the direction of spread, and the magnitude of displacement on the reverse design elements specific to this die.
