1964-D Doubled Die Reverse DDR-006

Description

Sixth in the reverse doubled die census for the 1964-D Roosevelt silver dime, DDR-006 shows medium spread on all outer rim lettering — encompassing UNITED STATES OF AMERICA, ONE DIME, and E PLURIBUS UNUM on John R. Sinnock's reverse featuring the torch flanked by olive and oak branches. VarietyVista assigned identifiers UVC-460 and DMR-008, documenting three die stages with particular detail: Stage A where the reverse is at early-to-mid die state (EMDS) with a straggly die crack running across the head to the rim at the K-1 position, Stage B at mid die state (unconfirmed), and Stage C at late die state (unconfirmed). The straggly die crack at the K-1 clock position provides a distinctive secondary diagnostic — "straggly" indicating the crack follows an irregular, branching path rather than a clean linear fracture. Denver struck approximately 1.36 billion dimes in 1964, the final year of 90% silver composition for the denomination before the Coinage Act of 1965 transitioned dimes to copper-nickel clad. The comments note "Obverse is ODV-011 (blunt 9)," identifying a specific obverse design variant characterized by a blunted numeral 9 in the date — a die preparation artifact where the 9 punch produced a slightly truncated or rounded lower loop. This dual attribution (DDR plus ODV) creates a die marriage with two independently attributable characteristics. Medium spread across all rim lettering indicates the secondary hub impression displaced uniformly around the periphery, suggesting a concentric or radial hub misalignment rather than a directional shift. Collectors should examine the lettering under moderate magnification while using the straggly die crack near K-1 as the initial die identification marker.
