1978 (D) Lincoln Memorial Cent - CU-1C-1978D-07 Cud

Description

Cataloged as CU-1C-1978D-07 by Cuds on Coins with an additional cross-reference to LC-78D-7B dated 09/01/2013, this cud variety documents the seventh confirmed rim break on 1978 Denver Mint Lincoln Memorial cents. The presence of the LC-78D-7B cross-reference indicates that this particular die break was independently documented outside the Cuds on Coins catalog system, with the September 2013 date marking when the cross-reference was recorded or confirmed. Multiple catalog entries for the same variety lend additional credibility to the attribution and provide alternative lookup paths for researchers working with different reference systems. Cuds are the product of terminal die failure: when a fragment of hardened die steel separates completely from the die rim under the cyclic stress of repeated striking, the resulting cavity fills with flowing planchet metal on each subsequent strike, producing a raised, featureless mass along the coin's edge. CU-1C-1978D-07's unique break geometry distinguishes it from the other entries in the 1978-D census, and the LC-78D-7B cross-reference provides an independent confirmation of its cataloging.
