What if my book has a COA (Certificate of Authenticity)?

Please do not send COAs to CGC along with your books. We will not need them and cannot guarantee that they will be returned along with your submission.

What measures are taken to protect my comics while they are held by CGC?

In addition to vault storage, CGC uses state-of-the-art security and surveillance equipment, and only the most highly trained professionals who understand the unique handling requirements of comic books will handle your comics. While at CGC, your books are always fully insured against theft or damage.

As an independent member of the Certified Collectibles Group (CCG), CGC benefits from the other member companies' decades of experience in thorough operations and careful handling of delicate collectibles. With the CCG companies successfully handling more than 100,000 fragile collectibles each month, you can be assured that we have the experience to treat your comic books with the respect and proper handling techniques to ensure their safety.

While CGC is responsible for the care of your books while they're with us, any damage that occurs during shipping to CGC or after the books leave our facility is your responsibility or that of the shipping company with whom you contract.

How does one become a CGC grader?

CGC primarily seeks graders who have experience in collecting and grading modern or vintage comics, or both. Knowledge of CGC's grading standards and services, comic book history, creators, restoration detection, pedigrees, variants and market values are considered important aspects of this experience. Newly hired graders are trained on CGC's exclusive grading standards before they become part of the team. If you think you may be a good candidate, please send us your resume:
