SKH-1c-1971D-33 Spiked Head

Description

Documented on August 12, 2019 — more than a year after SKH-32 — SKH-1c-1971D-33 on the 1971-D Lincoln Memorial cent demonstrates that the spiked head discovery process for this date continued well beyond the initial 2017-2018 discovery wave. Attributed by Cuds on Coins, this thirty-third entry arrived during a period when the most concentrated searching had subsided, making it likely the product of either a newly examined accumulation of 1971-D cents or a collector encountering the variety independently and recognizing it as a previously undocumented spiked head. The extended timeline of discoveries — from 2016 through 2019 and beyond — reflects the practical reality that the 1971-D's massive surviving population will continue yielding new spiked head varieties for as long as dedicated examiners apply systematic scrutiny to this date. No cross-references to other attribution catalogs have been recorded. Each new entry at this depth in the sequence incrementally extends the statistical picture of die crack behavior across Denver's 1971 obverse die population, adding another unique crack geometry to a dataset that already documents more than thirty instances of the same failure mode manifesting differently across thirty-plus individual dies.
