RIDB-1c-1960-03(LD) Cud
Error
Description
The companion listing to the retained interior die break entry, RIDB-1c-1960-03(LD) Cud on the 1960 Lincoln Memorial Cent Large Date documents the same die in a more advanced state of failure where the die fragment has fully separated. A cud occurs when a piece of the die's face breaks away completely, leaving a void in the die surface. Coins subsequently struck by this damaged die exhibit a raised, featureless blob of metal in the area corresponding to the missing die fragment — a distinctive error that is immediately visible to the naked eye without magnification. This cud listing and its paired retained interior die break entry (RIDB-1c-1960-03(LD)) together document two stages in the life of a single deteriorating die: first the fragment cracked and shifted while remaining attached (the retained break stage), then it separated entirely (the cud stage). Cataloged by Cuds on Coins with the cross reference date of January 16, 2017, the Large Date regular strike designation places this error in Philadelphia's first production phase of 1960. Collectors who acquire both stages from this die possess a particularly instructive pair that illustrates the progressive nature of die failure — from initial crack formation through fragment retention to complete separation and the characteristic raised metal blob that defines a cud error.
