Professional Sports Authenticator (PSA) is one of the most respected card grading services.
Details
PSA grades cards on a scale from 1 to 10, with 10 being gem mint condition. Factors considered include centering, corners, edges, and surface quality. PSA-graded cards often command higher prices in the secondary market. Their online submission process allows collectors to easily submit cards for grading, and their population reports provide valuable data on the rarity of certain grades for specific cards.
