CU-10c-1972D-01 Cud

Description

Cross-referenced as RDC-72D-1 in the Roosevelt Dime Cud registry and first cataloged by Cuds on Coins on September 1, 2013, this cud error on the 1972-D Roosevelt Dime records a die break at the rim where a section of the die fractured and separated, producing a raised featureless area on struck coins where the missing die fragment once carried design detail. The 1972-D belongs to the clad era of Roosevelt Dime production, struck in the copper-nickel clad composition (outer layers of 75% copper / 25% nickel bonded to a pure copper core) at 2.27 grams — the standard that replaced the pre-1965 silver composition under the Coinage Act of 1965. The Denver Mint's 1972 dime production was substantial, with over 330 million pieces struck, requiring a large number of die pairs and consequently creating numerous opportunities for die failures including cuds, die cracks, and other progressive deterioration features. As the first cataloged cud for the 1972-D Roosevelt Dime (denoted by the "01" suffix), this variety establishes the primary entry in the cud census for the date. Cuds on copper-nickel clad planchets can present differently than those on silver issues — the harder clad composition sometimes produces sharper edges around the cud boundary and can retain finer detail in the transition zone between the cud's featureless plateau and the adjacent normally struck design. The RDC cross-reference number connects this variety to the broader Roosevelt Dime Cud database, facilitating comparison with other rim breaks across the full span of the series. Collectors can identify this cud by locating the smooth, raised mass at the rim and confirming the absence of normal design detail within the affected zone under standard magnification.
