1971-D Doubled Die Reverse DDR-001

Description

Primary doubled die reverse for the 1971-D Kennedy Half Dollar in the clad composition series, DDR-001 displays medium spread on all letters and stars around the rim, designer's initials, arrows, and clouds — a comprehensive doubling effect that touches virtually every reverse design element. VarietyVista assigns UVC-171 and DMR-004, tracking three die stages: Stage A at early die state (unconfirmed), Stage B showing the reverse at mid-die state with the obverse listed as DDO-002 at MDS, and Stage C with both reverse and obverse at late die state. The obverse is additionally identified as ODV-003 and listed as DDO-002, making this another consequential die marriage where both dies carry independently cataloged doubled die characteristics. The 1971-D Kennedy Half Dollar marked the early clad era of the series — Denver struck clad-composition halves beginning in 1971 after the silver content had been eliminated for business strike halves (40% silver halves continued in collector sets through 1970). Frank Gasparro's heraldic eagle reverse, with its extensive rim lettering (UNITED STATES OF AMERICA and HALF DOLLAR), thirteen stars, arrows, olive branch, and clouds, provided numerous design elements across which the medium spread manifests. The DDR-001 designation as the primary doubled die reverse for the date indicates this is the most significant or earliest-cataloged reverse doubling variety, and its pairing with DDO-002 on the obverse creates a dual-sided doubled die coin of particular interest to Kennedy Half specialists. Medium spread affecting the designer's initials (FG for Frank Gasparro) at the lower right of the reverse provides a quick attribution check point.
