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 — one of the most immediately recognizable error types in all of numismatics. Philadelphia struck its 1975 cents without a mint mark, consistent with the convention that prevailed until 1980 when the "P" designation was first added to the denomination. 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. Ten documented cuds for a single Philadelphia date represents a substantial census and places the 1975 cent among the more extensively cataloged dates for rim break errors in the Lincoln Memorial cent series. 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.
