CSG is an expert, impartial and efficient third-party authentication, grading and encapsulation service for sports cards. We are backed by the same ownership and senior management team behind NGC, PMG and CGC — the world’s leading and largest coin, paper money and comic book certification services.
CSG uses world-class expertise, advanced technology, innovation and operational excellence to provide sports card collectors and dealers with accurate, consistent and fast certification services. We also offer the industry’s strongest guarantee, which adds significant confidence, liquidity and value to the hobby.
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.
After a card has been authenticated and graded by CSG, it is encapsulated in the archival, durable and crystal-clear CSG holder. An enclosed certification label provides a detailed description of the card, its grade, its unique CSG certification number and a QR code to facilitate quick verification. The CSG holder and label feature extensive security elements to prevent against tampering and counterfeiting.
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.
