Slowking Prime #85/90 Holofoil price and PSA 10 value

Slowking Prime 85 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 Premier ($599), so your all-in cost is $729.

Grade	Sells for	PSA fee at that value	You make
PSA 10	$8,600	Premier $599	+$6,752.68
PSA 9	$1,366	Priority $79.99	+$978.11
PSA 8	$423	Standard $59.99	+$177.28

The slab has to sell for at least $838 to break even. A PSA 10 sells for about 69 times the raw price, and a PSA 9 for about 10.9 times.

Other grades: a 9.5 sells for about $1,503 and a BGS 10 for about $11,180.

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.
