1964 Doubled Die Reverse WDDR-009
ErrorDescription
Struck as a proof at the Philadelphia Mint in the final year of 90% silver dime production, WDDR-009 on the 1964 Roosevelt Dime displays notching on the upper letters of UNITED with light extra thickness on E PLU. Die markers on the obverse include a blunt tail on the 9, though no other significant obverse markers have been noted. Reverse markers include a short die gouge extending south from the rim above I in UNITED and die pitting on the M in AMERICA. Cross-reference: Wexler Variety ID: 1964 10¢ Pr WDDR-009. Notching—a form of doubling where the letter serifs show step-like irregularities rather than smooth curves—is a diagnostic hallmark of certain doubled die classes and provides attribution evidence even on well-circulated examples where broader spread might be worn away. The 1964 proof Roosevelt Dime was the last silver proof dime produced before the composition change to copper-nickel clad in 1965, marking WDDR-009 as one of the final silver proof doubled die reverses in the denomination's history. Philadelphia Mint proof production. Attributed by Wexler Team.
