CU-25c-2001P-02R(KY) Cud

Description

Second documented reverse cud on the 2001 Philadelphia Mint Kentucky State Quarter, CU-25c-2001P-02R(KY) represents a different die pair than the -01R variety, as each catalog number corresponds to a distinct die exhibiting its own fracture pattern. The sequential numbering system assigns each newly discovered cud from a given date, mint, and denomination a consecutive number, with the "R" suffix specifying reverse-die origin. Two reverse cuds from the same issue indicate that at least two different reverse dies developed rim fractures severe enough to separate before being pulled from service. The Kentucky quarter reverse, designed by T. James Ferrell, shows a horse and fence scene occupying much of the die surface, leaving the rim to absorb the full force of the striking collar. Die rim fractures on modern clad quarters typically originate at stress concentration points where the rim meets the collar interface, and repeated high-speed impacts propagate cracks until a section breaks free. The resulting cud — a raised blank area where the broken rim once stood — is unique to the specific die and failure stage, making each cataloged cud an individual record of die deterioration.
