IDB-1c-1955-10R Interior Die Break

Description

Cataloged as IDB-1c-1955-10R, this interior die break appears on the reverse of a 1955 Lincoln Wheat Cent. Unlike cuds — which form when die fragments break away at the rim — interior die breaks occur entirely within the die face, away from the edge, creating raised irregular shapes surrounded by normal design detail on all sides. The distinction is significant: rim breaks result from leverage at the die's unsupported edge, while interior breaks require internal stress fractures to propagate through die steel far from any free boundary. The "R" suffix confirms this variety affects the reverse wheat-ears design rather than Lincoln's portrait. Interior die breaks on Wheat Cents attract specialized collectors who document die failure patterns that high-volume production generated. The 1955 date is perhaps the most scrutinized in Lincoln Cent numismatics owing to the famous 1955 Doubled Die Obverse, and that attention has yielded documentation of numerous secondary varieties including die breaks and other deterioration phenomena. Cataloged and verified by Cuds on Coins.
