CU-1C-1980-01 Cud

Description

First in the documented rim break census for the 1980 Philadelphia Mint Lincoln Memorial cent, CU-1C-1980-01 is cross-referenced as LC-80-1A by Cuds on Coins, indicating it was among the earliest 1980 Philadelphia cuds to enter the research literature. The dual designation reflects the catalog's evolution — LC-prefixed numbers derive from an older classification system that was later superseded by the standardized CU-1C format. A cud results from the complete separation of a die rim segment, leaving a void in the die that fills with planchet metal under striking force to produce a raised, featureless mass along the coin's edge. The 1980 Philadelphia cent holds special significance in Lincoln cent collecting as the first year the P mintmark appeared on the denomination, ending nearly two centuries of tradition in which Philadelphia coins carried no mint identification. The high production volume for this inaugural P-mintmark year consumed a substantial number of die pairs, and the statistical inevitability of terminal rim fractures across such a large die inventory is reflected in the multiple cuds documented for this date. CU-1C-1980-01 is identified by the specific angular position and extent of its rim separation as documented in the Cuds on Coins reference photographs. The coin was struck from the standard 95% copper alloy. Attribution by Cuds on Coins.
