1975 Lincoln Memorial Cent - CU-1C-1975-10 Cud

Description

Cataloged as CU-1C-1975-10 by Cuds on Coins, this cud variety documents the tenth confirmed rim break on 1975 Philadelphia Mint Lincoln Memorial cents. A cud is a major die break error caused by the complete separation of a fragment of die steel from the rim, leaving a cavity at the die's periphery that fills with planchet metal during subsequent strikes. The result is a raised, featureless mass of metal along the affected portion of the coin's rim. Philadelphia struck its 1975 cents without a mint mark, consistent with the convention that prevailed until 2017, when the "P" designation was first added to the cent. The enormous production volume at Philadelphia during 1975 demanded continuous rotation of die pairs through high-speed presses, and the cumulative mechanical stress of hundreds of thousands of strikes per die made rim fractures an inevitable byproduct of the production cycle. Each entry in the catalog documents a unique die that reached terminal failure, and CU-1C-1975-10 occupies its own distinct clock-position on the die rim, distinguishable from the other nine entries by the specific geometry and location of its break.
