1960 Proof Jefferson Nickel - Doubled Die Reverse WDDR-033

Description

Attributed by Brian A. Ribar on a proof 1960 Jefferson Nickel, WDDR-033 displays very close Class II distorted hub doubling on UNITED STATES. Class II doubling results from deformation within the hub under the massive tonnage applied during die sinking, producing a spread that typically radiates toward or away from the center of the design. The very close nature of this doubling means the separation between primary and secondary impressions is minimal, requiring careful examination under magnification against the proof coin's mirror-like surface to detect. Die markers include a slanted die scratch inside the long left window and a die scratch above the long right window of the Monticello building on the reverse — two architectural details that serve as reliable attribution confirmations. No significant obverse markers were noted. Thirty-three doubled die reverses cataloged for the proof 1960 Jefferson Nickel reflects the extraordinary scrutiny applied to early 1960s proof issues, which were produced in growing quantities as the United States Mint expanded its proof set program to meet rising collector demand. The proof surface provides an ideal medium for detecting Class II distortion, as even very close doubling creates visible edge effects against the reflective field. The Monticello building's architectural details — windows, columns, and inscriptions — provide numerous reference points where subtle doubling can be identified and measured, contributing to the depth of DDR documentation on proof Jefferson Nickels from this era.
