1975 (D) Lincoln Memorial Cent - CU-1C-1975D-09 Cud

Description

CU-1C-1975D-09 is a cud on the 1975-D Lincoln Memorial cent. 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. 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. Attribution by Cuds on Coins.
