Slab history — PSA 9 copies that have sold more than once

3 slabs have sold more than once, across 4 resales — typically 182 days apart, with a median gross price change of +38.2%. That is 3 of the 6 distinct slabs behind 10 cert-linked sales at this grade — 50%. The rest we have seen sell once, which is not evidence they have not sold before.

Cert	Sales of this slab	Between	Gross change
#74299654	Apr 2025 $420→Sept 2025 $390	3–6 months	-7.1%
#85488724	Jun 2024 $585→Sept 2024 $499→Mar 2025 $689	6–12 months	+17.8%
#23241735	Apr 2019 $53→Feb 2025 $630	Over a year	+1088.7%

A cert reappearing shows the same physical slab sold again — it identifies no buyer or seller. Gross change is price to price; fees, shipping and the grading cost are not in it.
