Collectors Holdings, the parent company of PSA, acquired SGC. The deal was announced by SGC on February 29, 2024.

The deal brings even more of the TCG card grading market share to the doorstep of the PSA brand. According to GemRate's X posts, PSA had 76% of the overall TGC grading market share and the acquisition of SGC will add another 2% to that total. In comparison, CGC had 18% of the total market in 2023, and Beckett took 5% of that market. A total of 8 million TCG cards were graded in 2023.

“Our portfolio focuses on service providers that bring expertise, quality and value to hobbyists, and SGC has built a strong reputation on these three fronts,” said Collectors CEO Nat Turner. “We recognize that every collector has their own preferred authentication and grading provider, and we look forward to providing expertise that will continue to enhance SGC’s customer offering.”

The addition of SGC turns Collectors Holdings into an even larger collectibles juggernaut. Collectors already owns PSA, PCGS, WATA (see "Collectors Universe Buys Wata Games"), Card Ladder, Goldin, and the Long Beach Expo. The acquisition of SGC strengthens their foothold as a leader in the collectibles space even further.
