Before you grade this card

Older cards often show edge wear, whitening on the back corners and light surface scratches from play and binder storage, so high grades are rare. Check all four back corners and tilt the card under a bright light before you pay a gem-mint price. 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.
