Weakness Guard 141 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 $79.65.

Before you grade this card

Vintage holos scratch easily and old print runs were often off-centre, so high grades are rare. Check the holo under a bright light and look hard at the back edges 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.
