CU-1C-1928D-02 Cud

Description

Nearing the end of the 1920s, Denver continued producing Lincoln Wheat Cents with dies that occasionally fractured at the rim — as documented by CU-1C-1928D-02, the second cataloged cud for the 1928-D issue. By this point in the series' history, the Lincoln Cent had been in continuous production for nearly two decades, and the Mint's experience with Victor David Brenner's design had established well-understood die-life expectations. Yet cuds remained an inevitable byproduct of the coining process because the rim area of any die faces unique mechanical challenges: it defines the boundary where the die cavity meets the collar, concentrating compressive and shear forces at every strike. No amount of metallurgical refinement eliminates the possibility of rim fracture entirely — it can only be managed through timely die replacement. The "-02" suffix in the Cuds on Coins designation confirms that a second die for the 1928-D cent developed a rim fracture severe enough to produce the characteristic raised mass of displaced metal, documenting a second failure event independent of the first cataloged cud for this date.
