CGC Comics

CGC, or Certified Guaranty Company, is a third-party authentication and grading service for pop culture and sports collectibles. Its experts evaluate an item’s authenticity and condition, then encapsulate it in a clear, protective holder with a label showing its description, grade, and unique certification number. CGC serves collectors and dealers across categories including comic books, magazines, trading cards, sports cards, video games, home video, posters, and pulps.

The company’s services are designed to help collectors protect, preserve, and present their items, while providing trusted grading information for buying and selling. Customers can submit collectibles through CGC’s online submission process, with membership options that may provide grading savings and other benefits. Once grading is complete, CGC securely packages and returns the items.

CGC emphasizes impartial assessments, specialist expertise, customer care, protective holders, and an easier submission experience. Its graded collectibles appear in auctions and online sales, where buyers and sellers can use the grade and authentication as part of evaluating an item. CGC is part of the Certified Collectibles Group.
