Raw price: $77.52 · PSA 10: no price data
PSA charges $80 and typical turnaround is approximately 75 business days. These numbers set the floor and the timeline — this is not an expected-value figure. The $80 fee is the same whether the card comes back a 10 or a 6.
This is not an expected-value calculation, and we are not telling you grading is a bad deal. A card that comes back 9 is not worthless, and we are deliberately not putting a number on that side today — our PSA 9 price data is not yet good enough to publish, and we would rather say so than estimate. This is one input, corrected: the odds of the top grade, measured on current submissions instead of a decade of them.
Two population snapshots per card, at least 30 days apart:
marginal rate = (pop10 now − pop10 then) / (total graded now − total graded then)
Restricted to cards with 20 or more newly graded copies in the window, so a card with three submissions does not produce a rate of 0% or 100% that means nothing. Full methodology at Pulse.
