Description

Die variety specialists screening 2016-P Harpers Ferry quarters identified yet another distinct doubled reverse — WDDR-027, cataloged under Wexler Variety ID 2016-P 25¢ WV WDDR-027. The systematic examination process involves reviewing coins under a stereo microscope at 10x to 20x magnification, methodically scanning each design element for traces of secondary hub impression. On the Harpers Ferry reverse, this means examining the fort's cupola, building rooflines, window grids, tree canopy outlines, and inscription lettering — each capable of registering hub misalignment differently depending on the doubling's direction and magnitude. During the ATB era, the U.S. Mint's die production facility in Philadelphia manufactured both obverse and reverse working dies, maintaining the entire chain from master to working die under a single operational roof. WDDR-027 represents one more data point in the extensive Harpers Ferry die study compiled through collaborative discovery and Wexler catalog submission.
