CU-1C-1951S-05R Cud

Description

Fifth reverse cud for the 1951 San Francisco Mint Lincoln Wheat Cent, this die break variety documents rim failure during one of the smaller-volume S-mint cent production years. San Francisco's role in cent production during the early 1950s was supplementary to the much larger Philadelphia and Denver outputs, and the lower die consumption that accompanied smaller mintages makes five documented reverse cuds a notable count for this facility. A cud forms when cumulative striking stress causes a crack to propagate from the die rim inward until a section of the rim separates entirely. The detached fragment leaves a cavity that fills with metal during subsequent strikes, creating the raised featureless blob that defines this error category. The "05R" suffix confirms this as the fifth reverse cud, building on four previously documented varieties for the 1951-S date. The 1951 cent was produced during the Korean War era, when military spending drove economic activity and sustained coinage demand. San Francisco's contribution to the cent supply helped meet this demand alongside the larger Philadelphia and Denver operations. Cross-referenced as CU-1C-1951S-05R and cataloged by Cuds on Coins, this variety is part of the comprehensive Wheat Cent cud census that tracks die rim failures across every date, mint, and die position in the 1909-1958 series.
