1944-S Doubled Die Obverse DDO-001

Description

Carrying the primary DDO position for the 1944-S Mercury Dime, DDO-001 shows light spread on the date beneath Liberty's portrait on Adolph Weinman's obverse. Cross-referenced as 1-O-II-C in CONECA — variety 1, obverse, Class II distorted hub doubling with counterclockwise spread, indicating lateral displacement without rotation across the date numerals. Die markers UVC-232 and DMR-004 confirm the working die. The reverse carries MMS-006, the "Ball Serif" mintmark style, where the S displays a rounded, ball-shaped terminal at the top of its serif rather than the standard flat or tapered finish. This mintmark variation provides a secondary confirmation checkpoint — collectors can identify the die marriage by matching both the light obverse date spread and the ball serif S. The 1944-S Mercury Dime was struck at the San Francisco Mint in 90% silver at 2.5 grams during World War II. Begin at the date under 7x magnification for Class II spread, then confirm the ball serif S mintmark on the reverse.
