CU-1C-1917S-08R Cud

Description

Cataloged as CU-1C-1917S-08R, this eighth documented rim cud from the 1917 San Francisco Wheat cent represents yet another unique die whose rim fractured during production. How are cuds measured and cataloged? The Cuds on Coins research team examines reported specimens under magnification, photographs the break from multiple angles, measures its approximate clock position on the rim, estimates its radial depth into the design field, and compares these parameters against all previously cataloged cuds for the same date and mint. If the break occupies a position not matching any existing entry, it receives the next sequential number. Size classifications range from tiny marginal cuds — barely visible notches at the rim — to major cuds that obliterate portions of lettering or design elements. The location of each break is unique to the specific die that fractured, since no two dies develop identical stress patterns even under similar operating conditions. For 1917-S cents, the accumulation of eight distinct rim breaks across different dies reveals the aggregate toll that sustained high-volume wartime production took on the San Francisco die inventory.
