CU-1C-1976-06 Cud

Description

Cataloged as CU-1C-1976-06 by Cuds on Coins, this sixth documented rim break on 1976 Philadelphia Mint Lincoln Memorial cents further extends the cud census for the Bicentennial year. Six cuds from a single Philadelphia date represents a substantial catalog of terminal die failures and places the 1976 cent alongside other high-mintage dates that generated significant die attrition during the Memorial cent era. The mechanism behind each cud is fundamentally identical — fatigue-driven crack propagation through the die rim culminates in the separation of a steel fragment — but the geometry of every break is unique, determined by the specific metallurgical characteristics, stress distribution, and microscopic flaws in each individual die. This uniqueness allows attribution services like Cuds on Coins to catalog and number each break as a distinct variety. The Philadelphia Mint's 1976 production ran at high volumes without a mint mark on the denomination, and the 95% copper composition provided a relatively soft planchet that nonetheless exerted tremendous force on the die surfaces through millions of striking cycles. CU-1C-1976-06 carries no additional cross-reference numbers from alternative attribution services and is documented exclusively within the Cuds on Coins system. Collectors should verify the break's angular position and the design elements affected to distinguish this variety from its five predecessors in the catalog. Attribution by Cuds on Coins.
