CU-1C-1975-14 Cud

Description

Representing the fourteenth cataloged rim break for the 1975 Philadelphia Mint Lincoln Memorial cent, CU-1C-1975-14 continues the extensive cud census for this high-mintage date. Fourteen cuds from a single date-mint combination is a noteworthy total that reflects the extraordinary die consumption rate at the Philadelphia Mint during the mid-1970s. Each cud in the census documents a distinct die that developed a terminal rim fracture — the catastrophic endpoint of a fatigue crack that propagated through the hardened die steel until a section of the rim separated entirely. Once the fragment detaches, the die continues to operate, but every coin it strikes carries a raised, formless mass of extruded planchet metal at the break location. The 1975 Philadelphia cent was struck without a mint mark from the standard 95% copper alloy, and the billions of cents required to sustain national commerce demanded continuous cycling of dies through high-speed presses. Under these conditions, rim fractures were a statistical certainty, and the fourteen documented entries for this date provide a tangible record of that attrition. CU-1C-1975-14 was cataloged by Cuds on Coins without additional cross-reference numbers from alternative attribution services. Collectors building a comprehensive 1975 Philadelphia cud type set will find that fourteen varieties offers one of the deeper catalogs in the Memorial cent series. Attribution by Cuds on Coins.
