CU-1C-1980-23 Cud
Error
Description
At census number twenty-three, CU-1C-1980-23 further cements the 1980 Philadelphia cent's status as one of the most well-documented dates for cud errors in the Lincoln Memorial series. The sheer volume of cataloged varieties for this single date invites questions about die management practices at the Philadelphia Mint during this period — were dies used beyond their optimal lifespan, were there metallurgical variations in die steel batches, or was the extraordinary production volume simply the dominant factor? In practice, all of these elements likely contributed. The Philadelphia facility struck billions of cents annually during this era, and with each die capable of producing several hundred thousand impressions before replacement, the statistical probability of encountering rim failures across the die inventory was substantial. CU-1C-1980-23 represents one such failure, its rim break position and extent confirmed as unique within the census. The coin was produced from 95% copper planchets bearing the P mintmark that first appeared on the cent denomination in 1980. Attribution by Cuds on Coins.
