Slab history — PSA 9 copies that have sold more than once
38 slabs have sold more than once, across 40 resales — typically 111 days apart, with a median gross price change of +28.8%.
That is 38 of the 574 distinct slabs behind 656 cert-linked sales of this card at this grade — 6.6%. The rest we have seen sell only once, which is not evidence they have not sold before.
A cert reappearing shows that the same physical slab sold again — it does not identify a buyer or seller, and PSA's feed carries neither. The change shown is the gross difference between two sale prices, before fees, shipping and any grading cost. Two sales of one cert less than 46 days apart are counted as one sale reported twice, not a resale.
