CU-1C-1976-07 Cud
Error
Description
Seventh in the 1976 Philadelphia Mint cud census, CU-1C-1976-07 records another die rim failure from the Bicentennial year's Lincoln Memorial cent production. With seven documented cuds, the 1976 Philadelphia date has built a rim break catalog that rivals those of other prolific years in the Memorial cent series. Each entry documents a unique die whose rim steel fractured and separated during service, leaving a void that produced the characteristic raised, amorphous mass of extruded planchet metal on every coin struck from the damaged die. The consistency of this failure mode across seven different dies illustrates a fundamental truth about high-volume minting: when die pairs are worked at the intensity required to produce billions of coins, a predictable fraction will develop terminal rim fractures as part of their normal life cycle. Cataloged by Cuds on Coins without additional cross-reference numbers from other attribution services, CU-1C-1976-07 adds another data point to the 1976 Philadelphia rim failure record. The denomination continued unchanged through the Bicentennial year — no commemorative modifications were applied to the Lincoln cent, unlike the quarter, half dollar, and dollar — and Philadelphia struck its cents without a mint mark from the standard 95% copper composition. Attribution requires careful comparison of the break's position and geometry against the reference record. Attribution by Cuds on Coins.
