SKH-1c-2023-12 Spiked Head

Description

Twelfth spike head variety documented for the 2023 Philadelphia Lincoln Shield cent, SKH-1c-2023-12 was cataloged by the Cuds on Coins service as part of the ongoing die failure census for contemporary cent issues. The Shield cent reverse, designed by Lyndall Bass and featuring thirteen vertical stripes within a Union Shield topped by a scroll reading ONE CENT, has been the standard reverse design since 2010, while Victor David Brenner's Lincoln portrait continues its unbroken run on the obverse that began in 1909. Modern coining technology at the Philadelphia Mint employs Schuler or Graebener presses capable of sustained high-speed operation, and the cumulative effect of millions of strikes on each working die ensures that fatigue-related failures like spike heads will occur at a predictable rate across the production year. The spike head formation at the apex of Lincoln's head follows the same mechanical principles that have generated this variety type for over a century: the thin wall of die steel between the deepest portion of the incuse portrait cavity and the surrounding field develops a crack under sustained percussive loading, and metal from subsequent planchets fills the widening fracture. Twelve documented spike heads for the 2023-P date suggests a typical frequency for a high-volume production year, though the catalog likely remains incomplete as collectors continue examining 2023-dated cents in circulation. Distinguishing a genuine spike head from a similar-looking post-strike damage mark requires the die-variety test: a spike head will appear identically positioned and shaped on every coin struck from that die, while random damage would appear differently on each coin. Collectors should look for the characteristic upward-projecting raised feature from Lincoln's hair under basic magnification.
