CU-25c-1983P-01A Cud

Description

Carrying the cross-reference designation WQC-83P-1 & 2R (Washington Quarter Cuds catalog), CU-25c-1983P-01A documents a rim cud on the 1983 Philadelphia Washington Quarter where a piece of the working die fractured and separated from the die face along the rim, creating a void that produced raised featureless metal on the struck coins. The "01A" suffix in the Cuds on Coins catalog typically indicates either a sub-variant or re-staging of the primary 01 entry, suggesting this cud may represent a different die stage of the same fracture documented under CU-25c-1983P-01, or a closely related but distinct break on the same die. The "1 & 2R" in the WQC cross-reference further suggests a relationship between two documented cud positions on the reverse of this date. The 1983-P Washington Quarter was struck during a period when the Philadelphia Mint produced quarters exclusively for circulation — no proof versions from San Francisco carried the P mintmark. John Flanagan's Washington obverse (introduced in 1932) and heraldic eagle reverse defined the quarter's appearance throughout the pre-State Quarter era. Rim cuds form through a progressive failure mechanism: microscopic stress fractures in the die steel propagate under the repeated impact of striking at pressures ranging from 35 to 55 tons, and once the fracture path reaches the die's edge on two sides of a region, the enclosed fragment can break free. Struck in copper-nickel clad composition (5.67 grams, 24.26 mm diameter, reeded edge), this quarter's cud is visible without magnification as an irregular raised mass at the coin's rim. The WQC cross-reference provides an additional attribution pathway beyond the Cuds on Coins catalog for collectors and researchers working with rim break documentation.
