CU-10C-1984-01R Cud

Description

Documented by Cuds on Coins with a cataloging date of October 1, 2013, CU-10C-1984-01R is a reverse cud on the 1984 Philadelphia Roosevelt dime — the "R" suffix confirming the die break occurred on the reverse die rather than the obverse. Reverse cuds on Roosevelt dimes affect the torch-and-branches design created by John R. Sinnock, and depending on the break's position around the rim, may obliterate portions of the lettering UNITED STATES OF AMERICA, the denomination ONE DIME, the motto E PLURIBUS UNUM, or the branch and torch elements themselves. No additional cross-references have been established beyond the primary catalog designation. The 1984 Philadelphia dime — struck without a mintmark, as was standard for Philadelphia coinage until the P mintmark was introduced on dimes in 1980 — saw a mintage of approximately 856 million pieces, a volume that required hundreds of die pairs over the production year. Reverse cuds on dimes are less frequently reported than obverse cuds, possibly because the obverse die (the hammer die, positioned on top in modern U.S. coinage) absorbs more impact stress per strike than the anvil die below, making it more susceptible to rim fractures. However, reverse dies also experience significant stress concentration at the rim, and examples like CU-10C-1984-01R confirm that reverse fractures do occur and can be dramatic enough to produce collectible cud errors that are visually compelling even on the dime's compact 17.91mm diameter.
