1973 (D) Lincoln Memorial Cent - SKH-1c-1973D-10 Spiked Head

Description

SKH-1c-1973D-10 is a spiked head on the 1973 Denver Lincoln Memorial cent, documented on December 29, 2023, by the Cuds on Coins attribution team. No cross-references to external attribution services have been assigned. The December 2023 date follows the ninth entry by approximately ten months (February 2023), suggesting continued periodic searching and discovery by collectors engaged with this date. SKH-1c-1973D-10's attribution required the Cuds on Coins team to verify that its spike's geometry — angle, length, width, base position, and curvature — did not match any of the nine previously documented entries. This differentiation becomes increasingly challenging as the catalog grows, since the range of possible spike geometries for a given die design is constrained by the fixed location of the portrait apex and the limited range of angles at which cracks can viably propagate through the die steel. Each new entry confirmed at this stage represents genuine additional documentation of the 1973-D die population's failure history.
