CU-5c-1979-01 Cud

Description

Cataloged by Cuds on Coins, CU-5c-1979-01 records a cud die break on a 1979 Philadelphia Jefferson Nickel — an issue that notably lacks a visible mintmark despite originating from the Philadelphia Mint, because the "P" mintmark was not introduced on Jefferson Nickels until 1980. The "-01" suffix in the catalog number indicates this is the first documented cud variety for the 1979 Philadelphia nickel, suggesting limited cud activity on dies prepared for this date. Cuds represent one of the more dramatic categories of die errors: a section of the die rim fractures and breaks away completely, leaving a cavity that fills with metal during the striking process to produce a raised, featureless mass along the coin's edge. The size and position of the cud vary with each die failure, making every cud variety unique. Felix Schlag's Jefferson portrait and Monticello design, by 1979 in continuous production for over four decades, provided the familiar canvases affected by this die failure. Cud collecting has developed a dedicated following, with Cuds on Coins maintaining the most comprehensive online catalog organized by denomination, date, and die number for systematic variety tracking.
