1940-S Doubled Die Reverse DDR-002

Description

Cataloged as DDR-002 for the 1940-S Mercury Dime, this variety presents a medium spread across STATES OF AMERICA, BUS of PLURIBUS, UM of UNUM, and the E of DIME on Adolph Weinman's fasces-and-olive-branch reverse. The doubling affects lettering in multiple inscription groups, providing several diagnostic checkpoints distributed across the reverse field. Cross-referenced under CONECA designation 2-R-II-C, identifying this as the second cataloged reverse variety of Class II distorted hub doubling, sub-class C. Class II doubling results from a tilted hub during die creation, producing distortion patterns that vary across the die surface based on each element's position relative to the tilt axis. Die markers UVC-270 and DMR-011 provide independent confirmation of the working die. This San Francisco Mint issue was struck in 90% silver at 2.5 grams, carrying Weinman's Winged Liberty obverse introduced in 1916. The medium-intensity spread across multiple inscription elements makes DDR-002 identifiable under moderate magnification — examine STATES OF AMERICA first for the strongest spread, then confirm the presence of doubling on BUS, UM, and the E of DIME for complete attribution.
