1972 Lincoln Memorial Cent - SKH-1c-1972-11 Spiked Head

Description

SKH-1c-1972-11 was attributed by the Cuds on Coins team on October 31, 2018 — approximately seven months after the rapid March 2018 cluster that produced varieties 08 through 10. No cross-references to other attribution services have been established. As the highest-numbered entry in the 1972-P spiked head catalog, SKH-1c-1972-11 represents the current boundary of documented die failures for this date and mint — though additional undiscovered varieties almost certainly exist within the enormous surviving population of 1972 Philadelphia cents. Each entry documents a distinct obverse die whose service life ended (or whose production was continued despite) the formation of a portrait-apex fatigue crack — the characteristic failure mode that unites all spiked head varieties regardless of date, mint, or position in the catalog sequence. At eleven varieties, the 1972 Philadelphia spiked head catalog stands as comprehensive documentation of the die failure phenomenon for this historically significant date — a date already famous for its extraordinary doubled die varieties and now equally well-documented for its portrait-region die deterioration patterns.
