1955 Doubled Die Reverse WDDR-004

Description

Fourth cataloged doubled die reverse for the 1955 proof Jefferson Nickel, this variety exhibits Class II Distorted Hub Doubling on UNITED STATES OF AMERICA, with closer doubling on FIVE CENTS and E PLUR of E PLURIBUS UNUM. The variation in doubling intensity across different reverse inscriptions — stronger on the peripheral legend and progressively closer on the denomination and motto — maps the geometry of hub distortion across the die face, with elements at different distances from the distortion point showing proportionally different displacement. Die markers include a slanted die gouge on Jefferson's cheek on the obverse and two die scratches above the small right window on the reverse, providing fixed diagnostics independent of the doubling. Philadelphia Mint proof production in 1955 served collectors through annual proof set sales, with each proof die receiving fewer total impressions than business-strike dies, limiting the population of any individual variety. Standard proof composition of 75% copper and 25% nickel. The multiple levels of doubling intensity across the reverse provide collectors with a mappable spread pattern that reveals the hub distortion's geometry — stronger effects near the rim and decreasing intensity toward the center of the die face.
