CU-25c-2001P-01R(KY) Cud

Description

First cataloged reverse cud for the 2001 Philadelphia Mint Kentucky State Quarter, CU-25c-2001P-01R(KY) documents a rim die failure on one of fifty quarters issued under the State Quarters Program from 1999 through 2008. Kentucky, the fifteenth state admitted to the Union in 1792, was honored with a reverse design by T. James Ferrell depicting a thoroughbred racehorse behind a plank fence with Federal Hill — the inspiration for Stephen Foster's "My Old Kentucky Home." The "(KY)" suffix in the catalog number identifies the specific state design, necessary because multiple states were released each year. A reverse rim cud forms when a section of the reverse die rim fractures and separates, leaving a cavity that fills with metal during striking to produce a raised featureless mass along the coin's edge. Philadelphia struck hundreds of millions of Kentucky quarters in 2001, and the sustained high-speed production created ample opportunity for die rim stress and fracture. State Quarter cuds became an active collecting specialty during the program's ten-year run, as each new design introduced fresh die pairs and new possibilities for rim failures across five annual releases.
