1975 (D) Lincoln Memorial Cent - CU-1C-1975D-04 Cud

Description

Bearing the catalog designation CU-1C-1975D-04 from Cuds on Coins, this cud variety marks the fourth documented rim break on 1975 Denver Mint Lincoln Memorial cents. The cross-reference notation for this variety indicates no additional catalog numbers have been assigned by other attribution services. The mechanism behind every cud is fundamentally the same — fatigue-driven crack propagation through the die steel culminates in the detachment of a rim section — but the geometry of each break is unique, determined by the specific stress patterns, metallurgical characteristics, and microscopic flaws in each individual die. This uniqueness is what allows attribution services like Cuds on Coins to catalog and number each cud as a distinct variety. CU-1C-1975D-04 continues the census of terminal die failures from Denver's 1975 production year, adding to the evidence that the mechanical demands of high-speed cent production pushed a measurable number of dies past their structural limits. Attribution by Cuds on Coins.
