1964-D Doubled Die Obverse WDDO-001
Error
Description
Carrying the primary obverse doubled die designation for the 1964-D Roosevelt silver dime, WDDO-001 presents a very close spread on the designer's initials (JS for John R. Sinnock) and the word TRUST from the IN GOD WE TRUST motto. The "very close" modifier indicates the primary and secondary hub impressions landed extremely near each other, producing enhanced thickness on the affected design elements rather than clearly separated doubled images — a subtle form of doubling that demands careful comparison against known normal specimens to confirm. The Wexler Team documented specific obverse die markers: die scratches running north-south to the left of the lips and chin on Roosevelt's portrait, plus a die scratch running southwest from the bottom left of the R in LIBERTY. No significant reverse die markers were noted. Denver struck approximately 1.36 billion dimes in 1964, the final year of 90% silver composition for the Roosevelt dime before the Coinage Act of 1965 transitioned the denomination to copper-nickel clad. The termination of silver dime production makes the 1964-D the last date where silver-composition Roosevelt dime varieties can be documented, lending historical significance to this WDDO-001 designation. As the primary obverse doubled die for the 1964-D date, this variety establishes the benchmark against which other potential doubled dies from the same issue are evaluated. Cross-referenced as Wexler Variety ID: 1964-D 10¢ WDDO-001. Collectors should first locate the die scratches near the lips, chin, and R of LIBERTY to confirm the correct die, then examine the JS initials and TRUST under at least 15-20x magnification, using oblique lighting to reveal the very close spread that thickens these design elements beyond their normal relief profile.
