When is come to getting a card graded there are 2 main company's used and 1 other that isn't used to often. the 2 that are used the most are Beckett Grading and PSA Grading, and the other grading company is Sports Card Guarantee. My personal favorite is Beckett because there are many different choices for grading types and the case that the cards are encased in look better that PSA and Sports Card Guarantee. Below I will post the website URL's to the 3 company's. Enjoy!
