CU-1C-1917S-10R Cud

Description

Tenth and highest-numbered in the 1917-S rim cud catalog represented in this batch, CU-1C-1917S-10R marks the upper boundary of documented die failures for a date that stands among the most prolific cud producers in the Lincoln cent series. Ten distinct rim breaks from ten different working dies — each verified independently by the Cuds on Coins research team — paint a vivid picture of a mint facility straining under wartime demands. The San Francisco Mint in 1917 occupied a granite-clad building on Fifth Street, its coining presses running continuously to meet Treasury Department requirements. Every one-cent die eventually reached a point of fatigue, and while most were retired before catastrophic failure, a meaningful number developed rim fractures producing cud varieties. The 10R designation represents the tenth confirmed instance for this date and mint — a count exceeding the total cud population for many entire decades of other denominations. Collectors assembling a set of 1917-S cuds face the challenge of locating ten distinct varieties, each originating from a different die and displaying a unique fracture geometry.
