CU-25c-1977D-01R Cud

Description

Cataloged as CU-25c-1977D-01R by Cuds on Coins, this rim cud on a 1977 Denver Mint Washington Quarter formed when a portion of the die fractured and separated at the rim during production. The missing die fragment left a void that filling planchet metal occupied during striking, producing the characteristic raised blob of featureless metal at the rim that defines a cud error. Washington Quarters, with their larger diameter compared to dimes and cents, present a broader rim surface area where stress concentrations can develop under the repeated impact of high-tonnage striking pressure. The 1977-D quarter was struck in the standard clad copper-nickel composition at the Denver Mint, carrying John Flanagan's classic Washington portrait and heraldic eagle reverse. Attributed by Cuds on Coins, this first-cataloged cud for the 1977 Denver quarter provides documentation of a specific die failure event from that year's production run. Cud collectors prize these varieties because each one is a physical record of a unique die fracture, unrepeatable once the broken die is removed from service.
