1964 Doubled Die Obverse WDDO-007

Description

Seventh doubled die obverse documented for the 1964 Proof Roosevelt Dime, WDDO-007 emerged from Philadelphia's proof production during the final year of 90% silver dime coinage. Proof dies undergo a more controlled manufacturing process than business strike dies, with polished fields and frosted devices, yet the hubbing stage remains susceptible to the same misalignment events that affect circulation dies. John R. Sinnock's Roosevelt portrait, with its distinctive ear detail, hair waves, and strong jawline, provides ample surface complexity where hub doubling creates detectable displacement. The 1964 proof set mintage was approximately 3.95 million, a substantial quantity that generated numerous die pairs. Seven documented DDO dies from this proof production indicates that even the more careful proof die preparation process could not entirely eliminate hubbing anomalies. No specific die markers have been cataloged for WDDO-007. Cross-referenced under the Wexler system as 1964 10¢ Pr WDDO-007, with no other known attributions. Proof DDOs often exhibit sharper doubling visibility due to the mirror finish of the fields. Attributed by the Wexler Team.
