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 100 distinct slabs behind 109 cert-linked sales at this grade — 1%. The rest we have seen sell once, which is not evidence they have not sold before.

CertSales of this slabBetweenGross change
#48951290Aug 2026 $372→Sept 2026 $485Under 3 months+30.4%

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.

How many PSA 9 copies exist

PSA’s cumulative census for this card. It counts resubmissions, so it skews toward nicer copies and overstates the rate a fresh submission should expect.

Share is each grader’s 9s out of everything it has graded. A 9.5 sits between a 9 and a 10; PSA does not give one. Another grader’s slab is its own market and is not in the price above. Totals include slabs graded authentic only.

Is the PSA 9 supply growing?

New PSA 9 slabs from PSA’s weekly counts, each change measured between the two report days shown; the weekly counts end on 19 Oct 2026, so the population above, PSA’s newest reading, can run ahead of them. Resubmissions count as new slabs, so this is the supply that reaches the market, not new copies of the card.

Our record holds the sales we can see (eBay, PSA’s cert-verified sales and the auction houses we read), not every sale, and most slabs graded are never sold.

Stepping up to a PSA 10

One grade apart, one Mewtwo. Today’s prices are each page’s headline; the line over time is our recorded price index for both grades.

A PSA 10 sells for $5,470 against $462 for a PSA 9: $5,008 more, or 11.8× the price of a 9.

PSA 10 price ÷ PSA 9 price
11.9×2.5×
1 Jan 202123 Oct 2026

On the index a PSA 10 was 11.8× a 9 on 23 Oct 2026, 7.7× on 24 Jul 2026, and 6.3× on 17 Oct 2025. A wider gap means the 10 has pulled further ahead of the 9.

  • PSA, CGC and Beckett side by side — each on its own population and fees, Beckett scored on the 9.5 its market pays for.
  • Lightly and moderately played — the same expected return for a copy that cannot gem.
  • Ask vs sold — what the live listings want, against what copies have really closed at.
  • Momentum — the 30-day median against the 90-day, per grade.
  • Where it sells higher — the Fanatics-versus-eBay premium, with the sale counts behind it.
  • Population history — the weekly PSA census, so you can see how fast 10s are arriving before you post the card.
