Blastoise #31/149 Reverse Holofoil price and PSA 10 value

Blastoise 31 grading math

Here is what you keep at each grade if you buy the card raw at today's price, pay PSA and $5 shipping, and sell the slab with a 13% selling fee. PSA's fee depends on what the card is worth after grading: it bills you up to the right tier if the card comes back worth more (the upcharge). PSA's cheapest open tier is Standard ($59.99). If this card grades a 10 it lands in Standard ($59.99), so your all-in cost is $102.

Grade	Sells for	PSA fee at that value	You make
PSA 10	$276	Standard $59.99	+$138.31
PSA 9	$159	Standard $59.99	+$36.72
PSA 8	$145	Standard $59.99	+$24.44

The slab has to sell for at least $117 to break even. A PSA 10 sells for about 7.5 times the raw price, and a PSA 9 for about 4.3 times.

Other grades: a 9.5 sells for about $175 and a BGS 10 for about $359.

PSA's cheaper Value tiers are paused right now. If they reopen (from $24.99 a card), a PSA 10 of this card would make +$173.31 and a PSA 9 +$71.72. PSA tiers checked September 20, 2026. See PSA grading cost and tiers and the full list of cards worth grading for profit.

Before you grade this card

Cards from this era often show edge wear and light surface scratches from play and binder storage. Check all four back corners for whitening. Graders score centering, corners, edges and surface, and the lowest of the four usually sets the grade. Our guide to card grading shows what to look for and compares PSA, BGS and CGC.
