CU-1C-1975D-02 Cud

Description

Recorded as the second cud in the 1975 Denver Mint census, CU-1C-1975D-02 documents another terminal rim fracture on a die used to produce Lincoln Memorial cents at the Denver facility. A cud results from the complete separation of a die rim fragment — a catastrophic structural failure driven by fatigue crack propagation through the hardened die steel. Once the fragment detaches, every subsequent coin struck by that die carries a raised, amorphous mass of metal at the break location, replacing the normal rim and whatever design elements occupied that portion of the die. The presence of a second cataloged cud for the 1975-D date confirms that multiple Denver dies reached rim failure during the production year, an expected outcome given the enormous volume of cents required to meet national demand. No additional cross-reference numbers from other attribution services have been assigned to CU-1C-1975D-02 beyond the primary Cuds on Coins designation. Collectors seeking this variety should compare the break's clock-position, angular extent, and the specific design elements it affects against published reference images, as the distinction between closely numbered cuds from the same date often comes down to subtle differences in the geometry and location of the rim break.
