SKH-1c-2023-11 Spiked Head

Description

Attributed by the Cuds on Coins service under catalog code SKH-1c-2023-11, this spiked head variety appears on a 2023 Philadelphia Lincoln Shield cent — a thoroughly modern issue demonstrating that spike head die failures remain a persistent feature of high-volume cent production. The Lincoln Shield design, inaugurated in 2010 with Lyndall Bass's Union Shield reverse and the continuation of Victor David Brenner's century-old portrait obverse, is manufactured at striking speeds and volumes that place extraordinary demands on working dies. Philadelphia produced billions of cents in 2023, and the mechanical stresses of modern high-speed coining presses — operating at rates exceeding 750 strikes per minute — create the conditions for die fatigue at predictable stress concentration points. The spike head phenomenon occurs specifically at the apex of Lincoln's head, where the deepest portion of the die's incuse portrait cavity meets relatively shallow adjacent field areas, creating a thin wall of die steel vulnerable to cracking under sustained percussive loading. When this wall fractures, subsequent strikes force planchet metal into the crack, producing the characteristic raised spike or horn that gives the variety its name. The eleventh documented instance for 2023-P suggests a typical rate of occurrence for a high-mintage date. Collectors hunting for spike heads benefit from the variety's visual accessibility — unlike many die varieties that require careful magnification and specialized lighting, a well-developed spike head can often be spotted at arm's length as an interruption in the smooth contour of Lincoln's silhouette. Confirming the attribution requires verifying the feature appears consistently on multiple specimens from the same die, distinguishing it from post-strike damage or planchet defects.
