CU-5c-1977-01 Cud
Error
Description
First documented cud on the 1977 Philadelphia Jefferson Nickel, CU-5c-1977-01 carries the cross-reference JNC-77-1 in the Jefferson Nickel Cud numbering system maintained by specialists tracking rim breaks across the denomination's production history. Philadelphia struck 585,376,000 nickels in 1977, a bicentennial-hangover year when production normalized after the special 1776-1976 commemorative issues that had disrupted normal scheduling across multiple denominations. The cud formed when a piece of the die fractured and separated at the rim, creating a void in the die face that filled with planchet metal during subsequent strikes — the resulting raised, featureless blob bears no design detail because the die material that would have imparted the design was no longer present. Cuds on Coins cataloged this variety as part of their systematic registry that tracks major die breaks by denomination, date, and mint across all United States coinage. Jefferson Nickels, struck continuously since 1938, have accumulated one of the most extensive cud registries in American numismatics due to the denomination's long production history and the relatively high die stress involved in striking the copper-nickel composition at high speeds. The "-01" suffix confirms this as the primary cud for the 1977 Philadelphia date, and the JNC-77-1 cross-reference enables researchers to locate this variety in both general and denomination-specific catalogs.
