1957 Doubled Die Reverse WDDR-021
ErrorDescription
Deep in the reverse doubled die census for the 1957 Jefferson nickel proof, WDDR-021 exhibits Class II (Distorted Hub) doubling with a close spread visible on E PLURIBUS UNUM and AMERICA. Class II doubling in the Wexler classification system results from a rotational distortion between hub impressions, where the working hub pivoted slightly during the secondary sinking, producing displacement that varies with distance from the pivot axis. Cataloged by Brian A. Ribar — a specialist in Jefferson nickel variety documentation — and cross-referenced as Wexler Variety ID: 1957 WDDR-021 Proof, this variety was struck as a proof at the Philadelphia Mint. Proof Jefferson nickels of the 1950s were included in the annual proof sets that saw increasing collector demand throughout the decade. The reverse die marker is particularly distinctive: a die dot positioned to the upper right of the second O of MONTICELLO on Felix Schlag's architectural facade. Die dots — tiny raised points on struck coins produced by small pits in the die surface — provide excellent secondary diagnostics because they are unique to individual dies and invariant across all specimens struck from that die. No significant obverse die markers were noted. The close spread classification indicates the secondary hub impression landed very near the primary position, thickening the letterforms of E PLURIBUS UNUM and AMERICA rather than producing clearly separated doubled images. Twenty-one cataloged reverse doubled dies for the 1957 proof Jefferson nickel reflects the intensive variety research that proof issues have attracted, as the mirror fields and frosted devices of proof coins provide high-contrast surfaces where even close-spread doubling becomes detectable. Collectors should first locate the die dot near the second O of MONTICELLO to confirm the correct die, then examine the motto and AMERICA under 15-20x magnification.
