RIDB-1c-1955-09 Cud

Description

Nine rim cuds cataloged for 1955 Proof Lincoln Wheat Cents reveals the extent to which proof dies were pushed during production that year. RIDB-1c-1955-09 documents the ninth distinct die that fractured at the rim, each one creating its own unique raised featureless area at a different position along the coin's edge. The Philadelphia Mint's proof operation in 1955 produced 378,200 proof sets, and the dies used to strike these coins endured the higher pressures and slower speeds required for proof quality, accumulating stress with each impression. By the ninth cataloged cud, the evidence points to a systematic pattern of rim fractures across multiple dies rather than isolated incidents, suggesting that the combination of die steel characteristics, striking pressures, and production volume created conditions conducive to rim failures. Each cud's rim position serves as its fingerprint, allowing collectors to distinguish one from another. Cataloged by Cuds on Coins for the Lincoln Wheat Cents 1909-1958 series.
