RCD-1c-1940S-89R Retained Cud

Description

Eighty-ninth in the catalog of retained cuds for the 1940-S Lincoln Wheat Cent, RCD-1c-1940S-89R stands near the summit of what may be the most extensively documented retained die break series for any single date-mint in American numismatics. Eighty-nine distinct working dies developed rim fractures where the fragment stayed in place — an astounding figure revealing how many dies were consumed and how systematically researchers examined surviving coins. The volume suggests metallurgical or operational factors at San Francisco in 1940 predisposed dies to rim cracking: perhaps die steel composition, heat treatment, or striking pressure created conditions where the perimeter was especially vulnerable. Each of these eighty-nine retained cuds occurs at a different clock position with fragments of varying size and depth, making the complete set a formidable collecting challenge. The catalog follows standard Cuds on Coins format — RCD for retained cud, 1c for one-cent denomination, 1940S for date and mint, 89 for sequence, R confirming retention. The coin was struck in 95% copper on a 19mm planchet.
