CU-100c-2007P-01R(JA) Rim Cud

Description

Cataloged by Cuds on Coins as CU-100c-2007P-01R(JA), this rim cud variety appears on a 2007 Philadelphia Mint Presidential dollar honoring John Adams, the second President of the United States. The Presidential dollar is struck in a manganese-brass clad composition weighing 8.1 grams with a 26.5 mm diameter and edge lettering containing the date, mintmark, and E PLURIBUS UNUM. The R(JA) designation in the catalog number indicates this cud is on the reverse die of the John Adams issue, with the parenthetical JA specifying which president's dollar is affected, a necessary clarification since four different presidents were issued each year. The reverse design, common to all Presidential dollars, features the Statue of Liberty designed by Don Everhart. A cud on a Presidential dollar is notable because the manganese-brass clad composition and the multi-layered construction of these coins create different failure characteristics compared to traditional copper or silver coinage. The cross-reference notes indicate no additional catalog numbers from other attribution services have been assigned, with a documentation date of December 10, 2018. The 2007 John Adams dollar was part of the Doubled Edge Lettering Inverted variety subtype, which refers to the edge inscription being struck twice or in an inverted orientation, a separate manufacturing anomaly from the rim cud itself but present on the same coin. The Presidential dollar program, which ran from 2007 through 2020, generated significant collector interest and was actively searched for errors and varieties during its initial years of circulation production. Edge lettering errors, off-center strikes, and die breaks including cuds were all documented on these coins, and the CU-100c designation within the Cuds on Coins system identifies this as a dollar denomination cud, systematically organized by denomination, date, and mintmark within their comprehensive die break database.
