1956 Doubled Die Reverse DDR-023
Error
Description
Cataloged by VarietyVista with attribution codes UVC-940 and DMR-027, this 1956 proof Jefferson Nickel doubled die reverse represents one of twenty-three doubled die reverses documented for the date. As a proof strike, this coin was produced at the Philadelphia Mint using specially prepared polished dies and planchets, struck multiple times at slower press speeds to achieve the mirror-like fields and frosted design elements characteristic of proof coinage. Doubled die varieties on proof coins carry special significance because proof dies are manufactured with the same hubbing process as business strike dies, meaning hub doubling can occur regardless of the intended strike quality. The 1956 proof nickel was part of the annual proof set sold directly to collectors, and the relatively small proof mintage compared to business strikes means fewer examples of any given die variety exist. Twenty-three doubled die reverses cataloged for a single proof date reflects intensive examination by specialists who recognize that proof coins' superior surface quality often makes doubled die features easier to detect than on business strikes produced at higher speeds.
