1963 Doubled Die Reverse WDDR-016

Description

Counterclockwise spread on USA and ONE DIME characterizes WDDR-016 on the 1963 proof Roosevelt silver dime, with a short vertical die scratch to the left of the O in OF providing the key reverse die marker. The CCW spread direction indicates the working hub rotated counterclockwise during the secondary impression, displacing the affected text in that rotational direction — visible as a consistent leftward shift of the secondary images relative to the primary when viewed with the coin oriented normally. John Sinnock's reverse design positions USA as an abbreviation within the UNITED STATES OF AMERICA legend, and the ONE DIME denomination occupies a prominent central position where the doubling should be most accessible for examination. The Wexler Team cataloged this as Wexler Variety ID: 1963 10c Pr WDDR-016, noting no significant obverse die markers. Philadelphia struck approximately 3.08 million proof sets in 1963, each containing a 90% silver Roosevelt dime. The vertical die scratch to the left of O in OF provides a rapid screening criterion — a short incuse line in the field adjacent to the preposition, oriented vertically against the curved path of the reverse inscription. This mark identifies the specific working die before the collector undertakes the more demanding examination of USA and ONE DIME for counterclockwise displacement. The high WDDR number of 016 for a single proof date reflects the extraordinary thoroughness with which the proof Roosevelt dime series has been examined, with the mirror-finish proof surfaces simultaneously enhancing and complicating doubled die detection depending on lighting conditions.
