Collectors Holdings, the parent company of PSA (Professional Sports Authenticator), has recently acquired two major competitor grading firms to dominate the market: <mark jsaction=”” jscontroller=”DfH0l” data-sfc-root=”c” jsuid=”fj0OVb_h” data-sfc-cb=””><strong jsaction=”” jscontroller=”zYmgkd” data-sfc-root=”c” jsuid=”fj0OVb_i” data-sfc-cb=””>SGC (Sportscard Guaranty Corporation) in February 2024 and <strong jsaction=”” jscontroller=”zYmgkd” data-sfc-root=”c” jsuid=”fj0OVb_j” data-sfc-cb=””>Beckett Collectibles (BGS) in December 2025</mark>. These acquisitions placed PSA, SGC, and Beckett under one umbrella, controlling approximately 75%–79% of the trading card grading industry.

And from what i have heard sgc is not more of a boutique. comix grading mostly.
