1978 (D) Lincoln Memorial Cent - CU-1C-1978D-01 Cud

Description

Cataloged as CU-1C-1978D-01 by Cuds on Coins, this variety documents the first confirmed rim break on 1978 Denver Mint Lincoln Memorial cents. The original catalog notation "number: none" indicates that no additional cross-reference number was assigned beyond the primary Cuds on Coins designation. A cud is produced when a fragment of die steel separates completely from the die's rim, creating a cavity that fills with planchet metal under striking pressure. Each working die endured hundreds of thousands of high-pressure strikes before retirement, and the cumulative fatigue loading inevitably produced terminal cracks at vulnerable points along the rim. CU-1C-1978D-01 initiates the cud census for the 1978-D date, and its specific break geometry — angular position, arc-length, and affected design elements — distinguishes it from subsequent entries. Denver's hand-punched "D" mintmark confirms the coin's origin. Attribution by Cuds on Coins.
