CU-10c-1997P-01R Rim Cud

Description

Documented by the Cuds on Coins research team, this 1997 Philadelphia Mint Roosevelt Dime displays a rim cud on the reverse — a major die break where a piece of the die fractured away at the rim, leaving a raised featureless blob at the edge of the struck coin. Rim cuds represent the most severe category of die breaks, occurring when accumulated stress causes a section of the die rim to crack and separate completely, creating a cavity in the die that produces an unstruck area filled with extruded metal on each subsequent coin. The 1997-P Roosevelt Dime was struck during a year when Philadelphia produced approximately 591.6 million clad dimes, continuing John R. Sinnock's enduring design that has appeared on the dime since 1946. Cuds are classified according to their location on the coin — obverse or reverse — and their size relative to the rim, with larger cuds generally commanding greater collector interest. The CU-10c-1997P-01R designation identifies this as the first documented reverse rim cud for the 1997 Philadelphia Mint dime. Unlike interior die breaks that produce raised lumps within the design area, rim cuds create a distinctive raised shelf at the coin's edge that obliterates whatever design elements occupied that section of the die, making them immediately identifiable even without magnification in many cases.
