1973-S Doubled Die Reverse DDR-001

Description

Progressive light spread characterizes this 1973-S Proof Jefferson Nickel DDR-001, with doubling increasing in intensity from left to right across E PLURIBUS UNUM, OF AMERICA, the S of CENTS, the right building edge of Monticello, and LLO of MONTICELLO. This left-to-right graduation pattern indicates the hub displacement followed a consistent directional vector, with elements positioned further along the spread axis receiving proportionally greater separation between primary and secondary impressions. Die markers UVC-1718 and DMR-007 provide independent identification of the working die. Felix Schlag's Jefferson portrait appears on the obverse of this 75% copper, 25% nickel coin struck at 5.0 grams. As a proof issue from the San Francisco Mint, this coin was produced with polished dies and planchets for inclusion in annual proof sets, meaning the doubled die originated in the die-making process rather than during striking. Examine the reverse inscriptions under magnification, noting how the spread intensifies progressively from left to right across the affected elements.
