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

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.

Stepping up to a PSA 10

One grade apart, one Nidoking. 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 $19,411 against $7,200 for a PSA 9: $12,211 more, or 2.7× the price of a 9.

On the index a PSA 10 was 2.7× a 9 on 23 Oct 2026, 4.6× on 19 Jul 2026, and 3.2× on 19 Oct 2025. A wider gap means the 10 has pulled further ahead of the 9.
