CU-10c-1990P-05R Cud

Description

Fifth reverse cud cataloged for the 1990 Philadelphia Mint Roosevelt Dime, CU-10c-1990P-05R represents a notably high count of reverse cuds from a single date. Five documented reverse die rim failures on 1990-P dimes suggest that a substantial number of die pairs were used and that rim fractures were a recurring issue during the year's production. Each cud forms independently when a die rim fragment breaks away, creating a unique raised featureless area at a specific position along the coin's rim. The location, size, and shape of the cud varies with each die failure, giving each variety its own distinctive appearance. Cataloged by Cuds on Coins, this fifth entry for 1990-P demonstrates the depth of die error documentation on Roosevelt Dimes. Philadelphia's dime production in 1990 was substantial, employing many die pairs across extended runs — and each die carried a statistical probability of developing the rim fracture that produces a cud. Collectors examining rolls and bags of 1990-P dimes have a better-than-average chance of encountering a cud variety from this well-documented date.
