CU-100c-1979D-09 Rim Cud

Description

Recorded by CudsOnCoins under the designation CU-100c-1979D-09, this Denver-mint Susan B. Anthony Dollar carries a cud error produced by a die rim break. When a segment of the hardened die fractures near its edge, the broken portion can no longer transfer design detail, resulting in a raised, featureless mass on the struck coin. The severity of a cud depends on the size and location of the break — some are small peripheral irregularities, while others obliterate substantial design elements. Frank Gasparro's Susan B. Anthony Dollar debuted in 1979 as a replacement for the large Eisenhower Dollar, introducing a smaller format intended for vending machine compatibility. Denver struck millions of the new dollar coins during the inaugural year, and the high production volume subjected dies to significant stress. The SBA Dollar's eleven-sided inner border — an attempt to distinguish it from the quarter by touch — and its distinctive eagle-landing reverse made it one of the most recognizable modern coin designs despite its controversial reception. As the ninth documented cud for the 1979-D issue, this variety adds to a growing record of die failure patterns on early SBA production.
