The Grading Companies
Beckett Grading Services (BGS), PSA and SGC are the main companies used to grade a card. In general, BGS is preferred for modern cards, while PSA is the favorite for vintage cards.
The Grading Scales
Beckett grades their cards on a scale of 1-10 with sub-grades (.5s). PSA Grades on a flat 1-10 scale and SGC Grades on a scale out of 100, which they then use to give the card a grade of 1-10.
Cards are graded based on these factors: Centering, Corners, Edges, and Surface. They give each attribute a grade of 1-10, then combine those to give the card a final grade of 1-10. Anything above a 9 is worth book value or greater, as BGS 9 (known as a "Mint 9") is the condition expected of the card out of the pack. A grade of 9.5 is Gem-Mint, which is a card that is nearly flawless. This is the condition most collectors want. Then there is a "PRISTINE 10" which is the holy grail of cardboard. Pristine 10s are rarely handed out. A Pristine 10 can turn a $10 card into a $1,000 one.
