CU-1C-1975-01 Rim Cud

Description

Titled as a "Rim Cud" in its original catalog listing, CU-1C-1975-01 inaugurates the rim break census for 1975 Philadelphia Mint Lincoln Memorial cents. Cataloged by Cuds on Coins, this variety records a complete rim fracture on a Philadelphia die — a die that struck cents without a mint mark, in keeping with the convention that prevailed until 1980. The "Rim Cud" designation in the title specifies that the break occurred at the die's outermost edge rather than as an interior design break, and the resulting error produces a raised, featureless mass of metal along the affected portion of the coin's rim. Philadelphia's 1975 cent production consumed an enormous number of die pairs running across multiple high-speed presses throughout the year, and each die absorbed hundreds of thousands of high-pressure impacts before retirement. Rim fractures were among the most conspicuous forms of terminal die failure, and CU-1C-1975-01 as the first entry in the Philadelphia 1975 cud catalog establishes the baseline for what would prove to be a multi-entry census of rim breaks from this date. Collectors encountering a suspected cud on a 1975 Philadelphia cent should compare the break's position and geometry against the reference images for all cataloged entries to ensure correct attribution.
