CU-10c-1990P-02R Cud

Description

Cataloged by Cuds on Coins as CU-10c-1990P-02R, this 1990 Philadelphia Roosevelt Dime displays a cud error on the reverse, the designation 02R indicating it is the second documented cud at a reverse rim position for this date and mint. Cuds form when a piece of the die breaks away at the rim, leaving a raised, unstruck blob of metal on the resulting coins where design detail that would normally be imparted by the now-missing die fragment is absent. Roosevelt Dimes struck at the Philadelphia Mint during this period were produced in copper-nickel clad composition on high-speed presses, and the mechanical stresses inherent in sustained production runs made dies susceptible to progressive cracking and eventual rim fractures. The position and size of the cud on this variety distinguish it from other known die breaks on 1990-P dimes. Collectors of cud errors prize Roosevelt Dimes because the small planchet diameter concentrates the cud's visual impact, making even modest die breaks appear proportionally significant against the compact design.
