CU-1C-1978-05 Cud

Description

Recorded as CU-1C-1978-05 in the Cuds on Coins catalog, this variety marks the fifth documented terminal rim fracture on 1978 Philadelphia Lincoln Memorial cents. Five distinct cuds from a single date-mint combination represents a meaningful census, indicating that the production campaign consumed dies at a rate sufficient to generate multiple terminal failures observable in the surviving coin population. Each entry in the census corresponds to a unique working die and a unique break event — no two cuds share the same die of origin, as each die can only fail at a given rim location once. The distinguishing characteristics between entries are the clock-position of the break relative to the obverse or reverse design, the angular extent of the separated fragment, and which design elements (if any) are obscured by the resulting extrusion. For CU-1C-1978-05, these parameters define its identity within the broader 1978 Philadelphia cud population. Collectors encountering potential specimens should note that cuds are permanent die characteristics — once formed, they appear identically on every subsequent coin produced by that die until it is removed from service. This repeatability means that multiple examples of CU-1C-1978-05 may exist, struck sequentially from the same damaged die before its retirement. The 1978 Philadelphia cent carries no mint mark and was struck from 95% copper planchets. Attribution by Cuds on Coins.
