CGC Signature Series®

The CGC Signature Series

Certified Guaranty Company (CGC), the leader in professional comic book certification, pioneered its respected Signature Series program, a certification service that assures the signature on a collectible is 100% authentic.

The foundation of CGC’s Signature Series program is the authorized CGC Witness. At comic cons or other authorized events, a CGC Witness or Facilitator will accompany the Collector to observe the signature(s). Once the witnessed signature(s) are obtain the collectible can be submitted to CGC for grading and certification with CGC’s prestigious Signature Series label. The book will then be encapsulated in CGC’s state-of-the-art, tamper evident holder to remain a treasured collectible for years to come.

CGC’s Signature Series program is available for comic books, magazines, posters, lobby cards and prints (prints submitted for CGC’s Signature Series will not be graded, only the signature itself will be certified.)

The CGC Signature Series

Note: In select instances, CGC may accept signed books directly from the signer/publisher if accompanied by the appropriate documentation, but generally the CGC Signature Series label will only be issued to books signed under the direct observation of a CGC representative.

Frequently Asked Questions About CGC Signature Series

  • What if I get the book signed before submitting the book to CGC?
    Unfortunately, if the signing is not witnessed by someone authorized by CGC, then the signature cannot be authenticated for the Signature Series label. Testimonials, photographs, and video recordings are not accepted.
  • What information goes on the label?
    The name of the person(s) who signed the comic, the date it was signed, and in some cases the location, such as the name of the convention or store.
  • Are restored comic books eligible for Signature Series?
    Yes. Restored comic books are eligible for the CGC Signature Series Restored label, which is yellow with a purple bar across the top. The degree of restoration and details of the work performed are noted on the label. As with all CGC Signature Series books, the signing must be witnessed by a CGC authorized representative.
  • What signings are approved for Signature Series?
    Most signings are prearranged. Any signing where a CGC witness is in attendance is eligible. This includes comic book conventions and public signings, such as ones at comic book store. In select instances, CGC may accept signed books directly from the signer/publisher.
  • How can I set up my own Signature Series signing?
    If you are already a CGC Member Dealer, it may be easier then you think! Call CGC Customer Service at 1-877-NM-COMIC to find out today.
  • How do I get my book signed if I am not going to a convention?
