1940-S Doubled Die Reverse DDR-001

Description

DDR-001 on the 1940-S Jefferson nickel reveals medium spread on PLURIBUS UNUM that increases progressively from left to right across the motto, a directional gradient characteristic of rotational hub doubling where the misalignment amplifies with distance from the pivot point. San Francisco struck approximately 39.7 million nickels in 1940, the third year of the Jefferson series. The progressive left-to-right intensification provides a valuable diagnostic — collectors can observe minimal doubling on the P of PLURIBUS, with the effect becoming increasingly pronounced through each successive letter until reaching maximum spread on the M of UNUM. VarietyVista catalogs this variety as UVC-660 with die marriage DMR-005. As DDR-001, it holds the primary position in the 1940-S doubled die reverse census. The rotational spread pattern documents a specific class of hub misalignment where the secondary impression was tilted relative to the primary, and the progressive intensification across the motto allows numismatists to reconstruct the approximate pivot point and rotation angle of the hub doubling event. Medium classification makes this variety detectable under standard magnification.
