CU-1C-1960D-01 Rim Cud

Description

Cataloged under CudsOnCoins reference CU-1C-1960D-01, this rim cud on the 1960-D Lincoln Memorial Cent Small Date bears the additional cross-reference number JCc-60Dsd-79 and was documented on September 1, 2013. A rim cud forms when a section of the die steel fractures along the rim and separates entirely, leaving a void in the die face that fills with metal during striking. The result is a raised, featureless blob extending from the coin's edge into the design field. Each cud is unique to the specific die that suffered the break, and the location and size of the raised area serve as the primary diagnostics for attribution. On the 1960-D Small Date cent, Denver's high-volume production subjected dies to intense mechanical stress, accelerating fatigue in the rim area where the die face meets the collar. Specimens should be examined under low magnification to determine the cud's clock position and extent, both of which help confirm this specific die rather than a different 1960-D cud variety.
