Comic Book Grading Services: CGC, CBCS, & JSA

We are pleased to announce that several of the major professional grading services will be on site at Planet Comicon Kansas City. These include CBCS, JSA, and One Stop Comic Shop – CGC Comic Book Submission & Signature Facilitator. Each will both have booths in the exhibit hall. We will post booth numbers as soon as they are available.

These companies will be taking submissions of comic books and other items for grading and will also provide a signature verification service for select creators at the show. More details on the signature verification service can be obtained at each booth.

Go through your collections, find those books you feel should be “slabbed” and bring them down to Planet Comicon Kansas City. Golden Age, Silver Age, Bronze Age, Modern Age – there are SO many books where value may be enhanced by having that book professionally graded.

Also, you may have your books signed by our prominent creators and obtain a witnessed signature for purposes of signature series slabbing.  There will be an additional fee from some creators for “witnessed” signatures. We have many creator guests who will attend the show for whom you might want autographs “witnessed” for slabbing purposes. The same applies to celebrity guests. If you wish to have a signature witnessed, Either CBCS or CGC can arrange for an authorized representative to observe the signing of the autograph and then the autographed item may be slabbed for signature series purposes.   There will also be an additional fee for the slabbing. 

NOTE:  Planet Comicon Kansas City is currently Jason Aaron’s only confirmed convention appearance for 2022.  We are quite pleased and grateful that he has chosen Planet for this appearance.  Jason has applied one restriction to his appearance.  He will not be signing any witnessed autographs at Planet Comicon Kansas City for slabbing purposes, by either CGC or CBCS.  He will sign items for fans at no charge, without witnessing, though he does suggest a donation to the Comic Book Legal Defense Fund.  He may limit the number of books he signs for one person at one time.
