1967 Lincoln Memorial Cent - SKH-1c-1967-04 Spiked Head

Description

Cataloged as SKH-1c-1967-04 and cross-referenced to the Cohen Index as 67-69 with a documentation date of April 1, 2016, this fourth numbered spiked head for the 1967 Lincoln cent is positioned within the sixty-ninth Cohen grouping for the date. This depth of coverage transforms the 1967 spiked head population into a meaningful research dataset: by analyzing the positions, angles, and sizes of spikes across dozens of different dies, researchers can draw conclusions about the stress distribution within cent dies and the typical failure modes of the die steel under the production conditions of the late 1960s. Each spiked head records a unique moment when a specific die's accumulated fatigue manifested as a visible fracture, and the aggregate pattern across all cataloged varieties illuminates the mechanical realities of high-volume coin production. The 1967 Lincoln cent was the final U.S. coin issue produced without mint marks under the Coinage Act of 1965; mint marks returned to all denominations in 1968. Attributed by Cuds on Coins. Struck on a 3.11-gram, 19mm planchet of 95% copper and 5% zinc.
