CU-10c-1955S-01 Rim Cud

Description

Cataloged as CU-10c-1955S-01, this rim cud on a 1955-S Roosevelt Dime carries particular historical significance: 1955 was the final year San Francisco struck Roosevelt Dimes before suspending coining operations until 1968. A rim cud forms when a section of the die edge fractures and separates, leaving a void that produces a smooth, raised mass of unstruck metal along the rim of every subsequent coin — a distinctive flat blob contrasting sharply with the normally detailed rim and adjacent design elements. San Francisco’s 1955 dime production was modest compared to Philadelphia and Denver output, giving all 1955-S die varieties a smaller surviving population. This first-cataloged rim cud for the 1955-S date documents a die that fractured along its periphery during the final production run of San Francisco dimes, and the terminal-year context adds collectible interest beyond the die break itself. Roosevelt Dime rim cuds are actively collected across all dates and mint marks, and varieties from low-production years or historically notable dates command heightened attention from specialists assembling comprehensive die break inventories.
