The toolbox
Free card grading tools
Small, fast tools for the two questions every collector asks before grading: is it centered enough, and will grading pay for itself?
Card centering calculator
Upload a photo, drag eight guide lines onto the card edges and the print border, and get exact left/right and top/bottom ratios. The table shows which PSA and CGC grades your centering allows, front and back.
Grading cost calculator
Choose PSA, CGC, SGC, Beckett or TAG and a tier, add the card's raw and graded sold prices and your honest guess at the grade, and see whether grading beats selling raw after fees and shipping.
