1966 Lincoln Memorial Cent - CU-1C-1966-07 Cud

Description

CU-1C-1966-07 is a cud on the 1966 Lincoln Memorial cent. A cud forms when accumulated metal fatigue causes a section of the die rim to fracture and separate entirely from the die body. The missing fragment leaves an open cavity in the die face, and when a planchet is struck against that damaged die, the metal flows into the void and produces a raised, featureless mass on the finished coin. The location and shape of the cud correspond directly to the geometry of the die fracture, making each cataloged cud a fingerprint of a unique die failure event. The 1966 Lincoln cent was struck at the Philadelphia Mint during the second year of the Coinage Act of 1965 era, when Congress had mandated the removal of mint marks from all U.S. coins to discourage speculative hoarding during the national coin shortage. Cross-referenced as CU-1C-1966-07 and attributed by Cuds on Coins. Struck on a 3.11-gram, 19mm planchet of 95% copper and 5% zinc.
