1925 (S) Lincoln Wheat Cent Rim Cud (Reverse 3:00)

Description

This 1925 (S) Lincoln Wheat cent displays a rim cud on the reverse at 3:00. The break sits in the rim at the right edge of the reverse, beside the wheat stalk, where the die lost part of its rim gutter. On the coin it appears as a raised interruption in the design rim that tracks the rim's course. Rim failures begin as fatigue cracks that nucleate at the die edge, where striking forces concentrate as the raised rim forms against the collar, and propagate through the hardened steel until a section detaches entirely. Position and angular width distinguish this break from the other San Francisco rim failures cataloged for the date, since each failed die produces a rim cud whose outline functions as a fingerprint for that specific die. San Francisco struck 26,380,000 cents in 1925.
