1964 Doubled Die Reverse DDR-001

Description

Holding the primary reverse doubled die designation for the 1964 Roosevelt silver dime, DDR-001 displays a complex spread pattern: light spread on UNITED, the left dot, and ONE, combined with extra thickness on the E and PLU of PLURIBUS and the left stem of the olive branch. John R. Sinnock's Roosevelt dime design, in continuous production since 1946, features a torch flanked by olive and oak branches on the reverse with the denomination ONE DIME centered below. VarietyVista assigned identifiers UVC-435 and DMR-019, documenting three die stages: Stage A with both reverse and obverse at early die state, Stage B at mid die state (unconfirmed), and Stage C at late die state (unconfirmed). The 1964 Roosevelt dime holds exceptional significance in American numismatic history — it was the final year of 90% silver dime production before the Coinage Act of 1965 transitioned dimes to the copper-nickel clad composition still in use today. Philadelphia's massive 1964 silver dime production of approximately 929.3 million pieces, ramped up to combat the national coin shortage, generated enormous die consumption that made hub doubling events statistically inevitable. The additional notation identifies the obverse as ODV-011 (blunt 9), indicating a specific obverse design variant where the numeral 9 in the date displays a characteristic blunt or squared-off terminal rather than the pointed or tapered finish seen on other die variants. This provides collectors with an independent obverse confirmation checkpoint. As DDR-001, this represents the premier reverse doubled die documented for the final silver dime, and the combination of multiple affected design elements and the historical significance of the 1964 date makes it particularly desirable for variety collectors.
