Description

Premier doubled die reverse for the 1970-S Kennedy Half Dollar, DDR-001 presents medium triple spread on UNITED STATES OF AMERICA and all the stars in the circle, with double spread on the stars between the rays and on HALF DOLLAR — a remarkably comprehensive doubling that affects nearly every major reverse design element. Triple spread on the inscriptions and circle stars means the hub impressed the die at three slightly offset positions, creating three overlapping images, while the denomination and inter-ray stars show the more typical double spread. VarietyVista catalogs this as UVC-164 and DMR-007, tracking three die stages: Stage A and Stage B both show the reverse and obverse in Early Die State (an unusual notation suggesting the die stages may overlap or the transition between stages is unclear), and Stage C in Late Die State remains unconfirmed. The comments identify this as a proof issue with the RDV-003 reverse die variety designation. The 1970-S Kennedy Half Dollar is exclusively a proof issue — no business strikes were produced at San Francisco for this date, making all 1970-S halves proof coins intended for collector sets. The silver-clad composition (40% silver) adds intrinsic value to the variety premium. As the DDR-001, this is the primary reverse doubled die for the date, carrying the highest significance designation among all cataloged 1970-S reverse doubling varieties. The proof striking process, with its polished dies and higher pressure, typically renders doubling more sharply defined than on business strikes, enhancing the visual impact of the triple spread.
