1971 Doubled Die Reverse DDR-001

Description

The primary doubled die reverse for the 1971 Kennedy Half Dollar business strike, the DDR-001 exhibits a medium spread on HALF DOLLAR and the stars in the heraldic circle, combined with a rotational spread on UNITED STATES OF AMERICA — two distinct doubling patterns on the same die indicating a complex hub misalignment during die manufacture. Cataloged by VarietyVista as UVC-400 with die marriage reference DMR-004, the obverse die is classified as ODV-002, placing it within a specific hub variant lineage. Three die states track the die's working life: Stage A in early die state is unconfirmed, Stage B shows both reverse and obverse in mid-die state, and Stage C confirms both in late die state. The 1971 Kennedy Half Dollar from the Philadelphia Mint was struck in copper-nickel clad composition — the first year without any silver content in half dollar production — marking a significant transition in the series. As DDR-001, this variety holds the top-ranked position for reverse hub doubling on the date, and the combination of linear spread on HALF DOLLAR with rotational spread on UNITED STATES demonstrates that the hub's misalignment involved both pivoting and tilting during the impression process.
