CU-25c-1990P-01R Cud

Description

Registered by Cuds on Coins as CU-25c-1990P-01R, this cud variety was struck at the Philadelphia Mint on a 1990 Washington Quarter. The -01R designation marks this as the first documented reverse cud for the 1990-P Washington Quarter. No separate cross-reference outside the Cuds on Coins system has been recorded. A cud is a category of die break in which a fragment of hardened die steel fractures away from the die face, creating a void that produces a raised, unstruck mass on coins struck from the damaged die. The size and location of the cud depend on where the fracture propagated through the die, with reverse cuds on Washington Quarters commonly appearing near design elements that create stress concentration zones — particularly around the eagle's wings, arrows, and olive branch. The 1990-P Washington Quarter was produced in clad composition at Philadelphia without a mintmark. As the first-documented cud for the 1990-P date, this entry establishes the baseline catalog record for any subsequent reverse die failures identified on this date and mint combination.
