CU-1C-1975-13 Rim Cud

Description

Titled explicitly as a "Rim Cud" in its original catalog listing, CU-1C-1975-13 is the thirteenth documented rim break on 1975 Philadelphia Mint Lincoln Memorial cents. The "Rim Cud" designation emphasizes that the fracture occurred at the die's outermost edge rather than as an interior die break where a fragment might separate within the design field while remaining partially retained by surrounding steel. Cataloged by Cuds on Coins, this variety skips past position 12 in the catalog sequence — the gap may reflect a variety documented in a different batch, a reserved position, or a retracted attribution. Rim cuds are created when a wedge-shaped fragment of die steel separates completely from the die's periphery, leaving an open cavity that allows planchet metal to extrude into a raised, amorphous mass during subsequent strikes. The size and visual impact of the resulting error depend on the dimensions of the separated fragment and the angular extent of the break around the die's circumference. Philadelphia's 1975 cent production ran without a mint mark and at volumes that consumed an extraordinary number of die pairs throughout the year. Thirteen confirmed cuds from a single Philadelphia date underscores the mechanical toll that high-volume production exacted on the mint's die inventory. Each documented variety represents a unique die failure event, and CU-1C-1975-13 adds to what is already one of the more comprehensive rim break catalogs in the Lincoln Memorial cent series.
