CU-1C-1978-02 Cud

Description

Designated CU-1C-1978-02 by Cuds on Coins, this variety documents the second confirmed terminal rim failure on 1978 Philadelphia Lincoln Memorial cents. The sequential numbering within the Cuds on Coins catalog reflects the order of documentation rather than chronological die failure, meaning CU-1C-1978-02 was the second variety reported and confirmed for this date rather than necessarily the second die to fail during the production run. Rim cuds are among the most collectible die failure varieties because their bold, unmistakable appearance makes them accessible to collectors at all experience levels — the raised blob of metal extruding from the rim is visible without magnification and immediately signals an abnormal striking event. The underlying die failure is permanent and progressive: once a rim fragment separates, the cavity in the die may enlarge with continued use as additional material fractures away from the break margins, potentially producing progressively larger cuds on later strikes before the die is finally retired. Collectors examining prospective specimens should compare the break's angular position and extent against the Cuds on Coins reference photographs, as the distinction between CU-1C-1978-02 and other entries in the 1978 Philadelphia cud census rests entirely on the geometry and location of the rim separation. All 1978 Philadelphia cents lack a mint mark and were struck from 95% copper planchets. Attribution by Cuds on Coins.
