CU-10c-1989P-01 Cud

Description

First cud variety cataloged for the 1989 Philadelphia Roosevelt Dime, CU-10c-1989P-01 documents a die break where a fragment of the die separated at the rim, leaving a raised area of unstruck metal on coins produced after the fracture occurred. Die breaks that produce cuds are the result of metal fatigue under the enormous pressure of high-speed coining operations — the die rim, being the thinnest and most exposed portion of the die face, is the most vulnerable point for crack propagation and eventual fragment detachment. The 1989 Philadelphia Mint operated at high production volumes, striking Roosevelt Dimes in the clad copper-nickel composition that has been standard since 1965. Attributed by Cuds on Coins, this variety carries the catalog designation CU-10c-1989P-01 and stands as the sole documented cud for this date and mint combination, suggesting the break was an isolated event rather than part of a systemic die quality issue. Collectors should inspect the rim area carefully under magnification, as the raised cud can range from a small bump to a substantial blob depending on the size of the missing die fragment.
