1960 Proof Jefferson Nickel - Doubled Die Reverse WDDR-040

Description

Class II distorted hub doubling producing tripling on E PLURIBUS UNUM and closer doubled spread on UNITED STATES OF AMERICA distinguishes this fortieth doubled die reverse for the 1960 Jefferson Nickel proof, documented by William Hostutler. Class II doubling, also known as distorted hub doubling, occurs when the working hub distorts under the immense pressure of the hubbing process, creating a spread that radiates outward from the center of the design rather than shifting uniformly in one direction. The tripling on E PLURIBUS UNUM indicates the hub engaged the die at three slightly different positions, leaving two displaced secondary impressions alongside the primary. The reverse die marker — a die dot in the upper right corner of the small right window on Monticello — provides a precise attribution reference point within Felix Schlag's architectural rendering. Cross-referenced as Wexler Variety ID 1960 WDDR-040 Proof, this variety confirms San Francisco proof production origin. The 1960 Jefferson Nickel proof was part of the proof set production that had resumed in 1950 after a wartime suspension, and by 1960 proof sets had become enormously popular with collectors. Forty documented reverse doubled dies for a single proof date is an extraordinary count, reflecting both the number of proof dies used and the intensity of examination these carefully preserved specimens receive. Class II tripling is considerably less common than standard Class II doubling, making this variety particularly notable for its multi-impression characteristics.
