Card Grading Companies
- Beckett Grading Services (BGS)
The Beckett name carries a lot of name in the world of sports cards and collectibles thanks to the publications and price guides that have served the hobby for years. Seeking to lend the value of that name to the card grading business, Beckett Media created Beckett Grading Services (BGS) in 1999, and it has been one of the leaders in its field ever since. - Global Authority
When card grading and authentication company Global Authentication (GAI) ran into financial trouble in early 2009, it attempted to file for Chapter 11 bankruptcy. But a judge threw out the filing, forcing it to find another option to continue operating. Part of the solution was to sell off the card grading arm, which was reborn under new management as a new business called Global Authority. - Professional Sports Authenticator (PSA)
In 1991, Professional Sports Authenticator (PSA) was created with an eye toward quantifying the condition of cards, and the concept proved so popular that the company is currently the largest third-party authenticator in the industry.
