About Fan Cave Expo

Fan Cave is a family-owned shop that has grown into one of the Midwest's top sports cards and collectibles stores since it first opened in 2016. As part of the store's growth, it also now hosts the Fan Cave Expo, which is one of the region's largest events for sports cards, autographed memorabilia and other collectibles. With more than 150 vendor tables to browse, buy, sell and trade, and autograph opportunities from local St. Louis sports stars, Fan Cave Expo is a can't-miss event!

Our representatives will be accepting submissions at the show. Bring your favorite collectibles to take advantage of fast turnaround times and save one way on shipping fees! Further instructions on the submission process are below.

JSA on-site services for autographed memorabilia

Submit autographed memorabilia for Basic Certification (COA), and items are processed and finalized the same day. Collectors can also submit items for the JSA Letter of Authenticity (LOA). These are observed the same day, with final documented results sent later by mail. Go to SpenceLOA.com/fees for submission pricing.

Preparing submissions for the show

Submit sports cards, TCGs and non-sports cards for CGC grading. Autographed cards may be submitted for CGC x JSA Authentic Autograph certification. Simply take the following steps before arriving:

1. Create a CGC account here. All it takes is a free account to submit, and paid members get additional discounts and benefits.
2. Go to the online submission form for cards. (For JSA memorabilia submissions, just bring your item to the show.)
3. Select “Mail-In or Show Drop-Off” to start your submission. Please note that you’ll have the option to choose JSA autograph authentication for cards after choosing your primary grading services.
4. Complete the submission form and print the packing slips.

Important: To ensure that your submission process stays on schedule, please place your collectibles in the order listed on the packing slip. Please bring BOTH copies of the packing slip with your collectibles to the show drop-off. Failure to do so will result in delays.


5. Keep your collectibles safe and secure until you drop off your submission (including the packing slip) with a representative.
6. Go to the Express Drop-off sign to finalize your submission.

All submissions will be transported to CGC’s headquarters in Sarasota, Florida, for authentication, grading and encapsulation.
