1971-S Doubled Die Reverse DDR-001

Description

Struck as part of the San Francisco Mint's annual proof set, the 1971-S Roosevelt Dime DDR-001 exhibits medium spread on STATES OF AMERICA, the torch flame tips, and the right laurel leaves — a substantial area of doubled imagery across the reverse legend and central device. Proof coins receive multiple strikes from specially polished dies against mirror-finish planchets, and when a proof reverse die carries hub doubling, the reflective fields make even moderate spread strikingly visible under magnification. Die markers UVC-558 and DMR-003 provide attribution points across three documented die stages. Stage A and Stage B represent Early and Mid Die State respectively, both currently unconfirmed, while Stage C shows both the reverse and obverse in Late Die State — the confirmed terminal stage where die wear has softened finer details. The progression from early to late die state on a proof die is notable because proof dies typically see far fewer impressions than business strike dies, meaning a DDR that spans EDS through LDS on proof production represents the die's full working life.
