2016 (P) Cumberland Gap National Historical Park Quarter - Doubled Die Reverse WDDR-013

Description

In the Wexler catalog for Cumberland Gap Quarter doubled die reverses, WDDR-013 (reference: 2016-P 25c KY WDDR-013) adds to a body of documented hub doubling events for this ATB design. No additional cross-references beyond the Wexler designation are known, which is typical for modern quarter varieties where the Wexler system serves as the primary attribution authority and alternative catalogs like CONECA have yet to assign separate designations to many recent discoveries. The Cumberland Gap reverse — depicting the Appalachian mountain passage that Daniel Boone helped popularize as a route for westward expansion — includes fine detail in the rock formations, distant landscape, and the frontiersman figure, all of which serve as potential carriers of doubled die displacement depending on the specific geometry of each hub misalignment event. The Philadelphia Mint's production of 2016 ATB quarters involved high-speed coinage presses running copper-nickel clad planchets at rapid cadence, and the working dies consumed across a full production run numbered in the hundreds, with each die passing through the hubbing process where misalignment could introduce doubling. WDDR-013 documents one such event. Examination under 7x to 10x magnification with oblique lighting best reveals the specific displacement pattern on this reverse die.
