SKH-1c-1960-02(LD) Cud

Description

Documenting the progressive die failure associated with the SKH-1c-1960-02(LD) spiked head die, this cud entry on the 1960 Lincoln Memorial Cent Proof Large Date captures the stage at which a section of the die broke away entirely. The spiked head feature — a die gouge or crack projecting outward from Lincoln's portrait — persists as a diagnostic marker, while the newly formed cud adds a raised, featureless mass of metal at the location of the missing die fragment. This dual-error combination provides a distinctive attribution profile: the spike identifies the original die anomaly, and the cud documents its subsequent structural failure. Cataloged under JC Cohen reference JCc-1960_067 with a date of January 16, 2017, the Cohen Index lists this variety as "Not Listed." The Proof Large Date classification places this coin among the specially struck proof issues at the Philadelphia Mint, where proof dies were typically limited to approximately 3,000 impressions before retirement. The constrained proof die life means that fewer specimens carrying this particular combination of spiked head and cud could have been produced compared to a business strike die that might have operated for tens of thousands of impressions.
