PSA grading is a grading and worth evaluation performed by the Professional Sports Authenticator, a third-party ranking system that ranks the quality of trading cards and other sports memorabilia. The PSA grading system has ten different levels of quality that are used to classify their own items as well as other items.
The PSA uses impartial third-party experts to do all of their grading to ensure that the entire process is unbiased. In addition, the company encapsulates all of the playing cards that it receives so that their condition can be maintained and they do not suffer any additional damage. The services of the PSA are useful to amateur sports memorabilia collectors who are interested in knowing what their collections are worth.
The PSA evaluates many different sports-related items, including cards, tickets, autographs, photos, bats, gloves, rings and trophies.
The grading system of the PSA works on a 1 to 10 scale, with 1 being the worst and 10 the best. Items that receive a 1 are considered poor, 2 is good, 3 is very good, 4 is very good-excellent, 5 is excellent, 6 is excellent-mint, 7 is near-mint, 8 is near mint-mint, 9 is mint and 10 is gem mint.
