CU-1C-1975D-09 Cud

Description

Ninth in the 1975-D Denver Mint cud census, CU-1C-1975D-09 brings the documented rim break count for this date to a substantial total that underscores the severity of die attrition during the production year. Cataloged by Cuds on Coins without additional cross-reference numbers, this variety records another instance in which a fragment of die steel separated from the rim and left a cavity that produced a raised, amorphous mass of metal on finished coins. Nine confirmed cuds from a single date-mint combination is a noteworthy census by any measure, and it places the 1975-D cent among the dates with the densest cud catalogs in the Lincoln Memorial cent series. The 95% copper planchet composition used for 1975 cents was softer than the zinc-coated steel used for certain wartime issues but harder than pure copper, and the repeated high-pressure impacts of striking this alloy contributed to the progressive fatigue that drove die rim fractures across the Denver Mint's press lines. Each of the nine cataloged cuds tells the story of a specific die reaching its structural endpoint — a silent record of the industrial scale at which American one-cent pieces were manufactured during the mid-1970s.
