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

1 slab has sold more than once, across 1 resale. That is 1 of the 11 distinct slabs behind 13 cert-linked sales at this grade — 9.1%. The rest we have seen sell once, which is not evidence they have not sold before.

Cert	Sales of this slab	Between	Gross change
#52869541	Jan 2022 $13→Apr 2025 $21	Over a year	+52.0%

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.
