1966 Lincoln Memorial Cent - CU-1C-1966-04 Cud

Description

Cataloged as CU-1C-1966-04, this is the fourth documented cud variety for the 1966 Lincoln cent from the Philadelphia Mint's peak-volume no-mint-mark production year. A cud is a die-failure variety that results from a rim fracture where a section of the die edge breaks away completely, and the void left by the missing fragment fills with metal during each subsequent strike. The resulting raised, smooth-surfaced protrusion on the finished coin replaces whatever design detail — rim, lettering, or devices — occupied that position, creating a permanent record of the die's structural failure. Cuds are particularly valued by error collectors because each one is a unique die event: no two dies fracture in exactly the same way, and the specific geometry of the break gives each cud variety its own distinctive character. Cross-referenced as CU-1C-1966-04 and attributed by Cuds on Coins. The 1966 cent was struck on the 95% copper, 5% zinc alloy adopted after the Act of September 5, 1962 removed tin from the cent. Struck on a 3.11-gram, 19mm planchet.
