Unlocking the Development Diagram ST10-014 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 $66.50.

Before you grade this card

These cards usually come out of the pack clean, so centering and print lines decide most grades. Check the borders left to right and top to bottom, and tilt the card under light to spot print lines and surface scratches on the foil. 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.
