DC-10c-2014P-01 Die Chip

Description

First cataloged die chip for the 2014 Philadelphia Mint Roosevelt Dime, DC-10c-2014P-01 documents a small raised bump on the coin's surface caused by a fragment of the die face breaking away during production. Die chips form through localized fatigue failure: repeated striking concentrates stress at points where design elements create thin sections or sharp internal angles in the die steel, and eventually a tiny piece of the die surface spalls off, leaving a small cavity that fills with metal under striking pressure. The resulting raised bump on the coin is typically small — often requiring magnification to detect — but its presence reveals information about the die's condition and production history that interests error and variety collectors. Cataloged by Cuds on Coins with the cross-reference designation indicating no known references to other attribution services, this variety belongs to the Roosevelt Dimes Clad and Silver Proof 1965 to Date series. John R. Sinnock's Roosevelt Dime design has been in continuous production since 1946, making it the longest-running active dime design in U.S. history. The 2014-P dime was struck on standard copper-nickel clad planchets, and Philadelphia produced hundreds of millions of dimes that year. While die chips are among the most common die errors encountered on modern coinage, formally cataloged examples with documented positions provide reference points for collectors who wish to attribute specific die pairings.
