1971-D Doubled Die Reverse DDR-006

Description

Exhibiting medium extra thickness on HALF DOLLAR, UNITED STATES OF AMERICA, and all the stars in the circle, the 1971-D DDR-006 Kennedy Half Dollar documents a doubled die reverse whose doubling affects multiple major design elements simultaneously. Cataloged by VarietyVista with die markers UVC-421 and DMR-017, the variety shows a complex die stage progression: Stage A in early die state (unconfirmed), Stage B where the reverse reaches mid die state and the obverse is listed as DDO-012 in mid die state, and Stage C where both reverse and obverse reach late die state. The obverse pairing with DDO-012 and ODV-003 means coins from this die pair carry both a doubled die reverse and a doubled die obverse plus an obverse die variety — a triple-variety specimen from a single die marriage. The 1971-D Kennedy Half Dollar was the first Denver Mint issue struck in copper-nickel clad composition, following the transition from 40% silver after 1970, with a substantial mintage of approximately 302.1 million coins. Gilroy Roberts's Kennedy obverse and Frank Gasparro's heraldic eagle reverse, with its encircling stars and HALF DOLLAR denomination, provide extensive design elements where the medium extra thickness from doubled die hubbing can be detected across multiple zones. Six documented doubled die reverses for 1971-D reflects the multiple die pairs employed during this high-production first year of clad composition, and the die marriage linking DDR-006 with DDO-012 creates a particularly desirable variety combination for Kennedy Half Dollar collectors pursuing dual-sided doubled dies.
