2011 Doubled Die Reverse WDDR-001

Description

First in the Wexler catalog for the 2011 Philadelphia Roosevelt dime under identifier 2011-P 10¢ WDDR-001, this doubled die reverse documents the primary DDR recognized for the year's production output. As the sole DDR cataloged for the 2011-P dime — no WDDR-002 or higher has been listed — it may represent an isolated hubbing anomaly from what was otherwise a clean die manufacturing year at Philadelphia. The 2011-P dime production run generated approximately 748 million coins, a volume consumed by several hundred die pairs rotated through the facility's high-speed presses. John Sinnock's reverse design had been in continuous use for sixty-five years by 2011, and the design's extreme familiarity among both Mint personnel and variety researchers means that doubling on this reverse is evaluated against an extensive body of comparative knowledge spanning six decades of production. No cross-references to CONECA, Cherrypickers, or other attribution services have been established, and no supplementary die markers have been documented for this variety. Hub doubling on the 2011 Roosevelt dime reverse would present on the same design elements that have characterized DDR varieties throughout the series: the torch flame contours, the leaf edges on the olive and oak branches, and the serif lettering of the inscriptions ONE DIME, UNITED STATES OF AMERICA, and E PLURIBUS UNUM. Detection requires comparison of suspect specimens against confirmed undoubled examples from the same date under matched magnification, looking for consistent, directional spread that repeats across multiple design elements.
