CGC and JSA take GalaxyCon St. Louis submissions October 23–25

CGC and JSA will accept submissions at GalaxyCon St. Louis on October 23–25, 2026. The venue is America's Center, located in St. Louis, Missouri.

How CGC submissions work

Submissions are handled by the CGC Facilitator Agents of Slabs, which will accept items at its GalaxyCon St. Louis booth.

Video games and home video collectibles are accepted by Agents of Slabs for CGC, as are TCGs, sports cards, non-sports cards, comics, and magazines. Per CGC, the facilitator has spent several years working with comic books, with a background that covers customer service, retail sales, and witnessing signatures for the CGC Signature Series.

Drop-off is a short process. At the booth, a collector completes a submission form and then gives the items to a staff member. The submission is tagged, and the customer gets a copy of the completed form. After purchase, the customer receives email updates on the order from drop-off through return shipping.

Once collected, all items travel to CGC's Sarasota, Florida headquarters, where they are authenticated, graded, and encapsulated. CGC's pitch for submitting at the show is quick turnaround times, plus one direction of shipping costs removed.

JSA autograph authentication on site

Representatives from JSA will be at the show to accept autograph submissions, answer questions, and authenticate signatures on site.

There are two routes. Under JSA Basic Certification (COA), autographed memorabilia gets processed and finalized on the day it is handed in. The Letter of Authenticity (LOA) from JSA is the slower option: staff look at the items the same day, yet the finished paperwork with the verdict is mailed afterward.

The announcement gives no JSA prices. Pricing is listed at SpenceLOA.com/fees.

The show around the booth

GalaxyCon St. Louis is a 3-day festival devoted to cosplay, gaming, anime, fantasy, sci-fi, pop culture, and comic books, according to its description. Attendees can expect hundreds of vendors and an artist alley, along with panels, cosplay contests, fan group meetings, and meetups with celebrities and voice actors.

Why it matters

The format matches the one CGC is using at other shows on the same weekend. TCGKing has covered CGC's submissions at Collect-A-Con Dallas and CGC and JSA at the East Bay Card Show, both on October 24–25. Those events route CGC submissions through FGS Autographs, with JSA handling autographs on site; St. Louis uses a different facilitator, Agents of Slabs.

CGC belongs to the Certified Collectibles Group, whose stated total since 1987 is over 110 million collectibles certified, across stamps, autographs, cards, comic books, banknotes, and coins.

What is still unknown

The announcement leaves several practical details open: the CGC grading fees and service levels available for show submissions, the exact turnaround times beyond "fast," the booth locations for Agents of Slabs and JSA, and the daily hours for accepting submissions. JSA pricing is also not in the announcement itself, only a link to a fee page.

What it means for collectors

• Put October 23–25, 2026 on the calendar and build your plans around the America's Center venue in St. Louis. Fees and hours from CGC haven't been announced yet, so contact the addresses above prior to bringing a big submission.
• Whether you play or collect, non-sports cards, sports cards, and TCGs can be handed over at the booth run by Agents of Slabs, which also takes home video collectibles, video games, magazines, and comics.
• Autograph holders who want a result on the spot should look at JSA Basic Certification (COA), which is finalized the same day. The LOA route takes longer, since final documents arrive by mail.
• Keep the copy of the submission form you receive at drop-off, and watch your email for order updates through return shipping.
