Expertise, Backed by Advanced Technology

Our graders’ expertise is backed by advanced authentication and grading technology to make the certification process more precise and efficient. For example, artificial intelligence (AI) automates many of the time-consuming aspects of sports card grading, such as attributing a card and measuring its centering. Meanwhile, forensic devices using UV light and infrared light reveal alterations and hidden details through ultra-microscopic inspections as well as non-destructive ink and paper analysis.

CSG Authenticity Grade Guarantee

The Strongest Guarantee in the Sports Card Grading Industry

Every CSG-certified sports card is backed by the CSG Guarantee of authenticity and grade, which is the strongest in the industry. The CSG Guarantee gives collectors and dealers greater confidence, making it easier and safer to buy, sell and collect sports cards.
