COMC is excited to announce we now accept cards graded by CSG Certified Sports Guaranty. CSG is backed by the same ownership and management team behind NGC, PMG and CGC who are branded leaders in coin, paper money and comic book certification services.

With 30+ years experience in certifying collectibles it was a logical extension for the founding group of NGC to expand services to gaming cards with CGC Certified Grading Company and sports cards under CSG (both accepted by COMC). Collectibles certified with CSG and CGC offer guarantees of authenticity and accuracy, as well as top-notch security elements to prevent against tampering and counterfeiting. COMC confidently welcomes cards graded by CSG to our marketplace!
