CU-100c-1979S-03 Rim Cud

Description

Cataloged as CU-100c-1979S-03 by CudsOnCoins, this San Francisco-mint Susan B. Anthony Dollar exhibits a cud error from a die rim break. San Francisco's role in SBA Dollar production included both business strikes and proof coins, and the 1979-S business strike carries the standard S mintmark without the mirror finish of proof issues. Cuds arise when the die edge fractures due to metal fatigue, heat cycling, or mechanical stress, and the broken zone ceases to impart design detail to struck coins. The third documented cud for the 1979-S issue, this variety adds to the growing die failure census across all three mints that produced Susan B. Anthony Dollars in the denomination's inaugural year. Frank Gasparro's design featured Susan B. Anthony on the obverse — making her the first historical woman portrayed on a circulating United States coin — and an adapted Apollo 11 mission insignia on the reverse. The eleven-sided inner border intended to aid tactile distinction from the quarter proved insufficient in practice, and the SBA Dollar's unpopularity limited its circulation life. San Francisco business strike SBA Dollars are less commonly encountered than Philadelphia or Denver issues.
