1977 Lincoln Memorial Cent - CU-1C-1977-16 Cud

Description

Closing out the 1977 Philadelphia cud census at its sixteenth catalog position, CU-1C-1977-16 records the final documented rim break for this high-volume production year. Cuds on Coins cataloged this variety as part of its comprehensive rim break inventory for the Lincoln Memorial cent series. A cud results from the terminal failure of a coinage die — the catastrophic separation of a rim segment that transforms the die from a precision tool into a damaged implement capable only of producing error coins. Each coin struck after the fracture event carries an unmistakable raised mass of metal at the break site, and the coins continue to accumulate until a press operator detects the defect and pulls the die from service. CU-1C-1977-16 is identified by its unique break geometry and angular position on the die rim. Like all 1977 Philadelphia cents, it was struck without a mint mark from 95% copper planchets.
