2015 Doubled Die Reverse DDR-037

Description

Medium westward hub doubling in the upper window R3 of the 2015 America the Beautiful quarter reverse marks this thirty-seventh doubled die reverse cataloged by VarietyVista for the date. The high sequence number — DDR-037 — testifies to the prolific variety documentation on ATB quarters, where each year's five unique scenic reverses provided abundant fine detail susceptible to hub doubling. Window R3 refers to a specific window position in an architectural feature of one of the 2015 ATB reverse designs (Homestead, Kisatchie, Blue Ridge Parkway, Bombay Hook, or Saratoga), and the westward directional spread indicates the hub shifted laterally during the second hubbing impression. Die stage documentation records UVC-2136, DMR-038, with Stage A showing both reverse and obverse at early die state, Stage B at mid die state (unconfirmed), and Stage C at late die state (unconfirmed). The ATB program ran from 2010 through 2021, producing quarters at both Philadelphia and Denver (plus San Francisco for collector editions), and the combined output across ten-plus years generated thousands of die pairs. Architectural windows on quarter reverses are among the design elements most sensitive to hub doubling because their rectangular geometry makes even slight displacement visible. Thirty-seven documented reverse doubled dies for a single year's ATB issues reflects the depth of the VarietyVista cataloging effort across this popular series.
