CGC, the world leader in professional comic book certification, pioneered witnessed signature authentication when it introduced CGC Signature Series in 2001. Since then, CGC has expanded its services for autograph collectors with the launch of JSA Authentic Autograph certification, a service for comics that have already been autographed.

CGC Services for Autograph Collectors

CGC Signature Series

Every year, fans bring their prized collectibles to comic cons and other pop culture conventions around the world. They travel far and wide with just one goal in mind — to have their collectibles signed by artists, writers, creators and celebrities. With CGC Signature Series, collectors can have their comic books, magazines, posters and prints signed by artists and creators in the presence of a CGC representative. The authenticity of the signature is then 100% certain, making the collectible eligible for the iconic CGC Signature Series yellow label.

CGC x JSA Authentic Autograph

CGC pioneered witnessed signature authentication when it introduced CGC Signature Series, but it had never offered full authentication and grading for collectibles with unwitnessed autographs — until the acquisition of JSA, the world leader in autograph authentication. The combination of CGC and JSA services is the answer to the countless collectors and dealers who have asked to have their autographed collectibles authenticated and then graded and encapsulated in one seamless solution.

The CGC Signature Series Label

The yellow CGC Signature Series label is given to collectibles that have been signed by someone of significance to the item. These labels will generally be issued only to items signed under the direct observation of a CGC representative. In select instances, CGC may accept signed books directly from the signer or publisher. The signatures are then authenticated by CGC with labels indicating who signed them, when they were signed and, in some cases, where they were signed.

After the collectible is signed in the presence of a CGC authorized witness, it is immediately submitted to CGC for expert grading and encapsulation in the state-of-the-art, CGC holder that bears the prestigious yellow label. Your collectible is then safely returned to you to become a treasured part of your collection.

The CGC x JSA Label

Autographed comics certified by CGC and JSA are encapsulated with the bold CGC x JSA Authentic Autograph black and yellow label, which is harmonious with — yet distinct from — the iconic CGC Signature Series yellow label. Collectors who submit autographed comics for either CGC grading or CGC Signature Series will receive the CGC x JSA Authentic Autograph label rather than receiving the CGC Qualified green label or the CGC Signature Series Qualified green and yellow label — another benefit of CGC x JSA certification.

When buying and selling autographed collectibles, CGC Signature Series and CGC x JSA are the best choice in the hobby!!
