About the Strongsville Sports Collectors Convention

The Strongsville Sports Collectors Convention is the premier vintage sports cards and memorabilia show and is also the longest-running event in the nation with a focus on vintage sports cards and memorabilia. Thousands of collectors and enthusiasts make the trek to see the top dealers, authenticators and auction houses all under one roof as well as gathering with friends from around the country who share a passion for vintage sports collectibles. In addition, numerous sports stars will make an appearance during the event, including several Ohio-based sports icons that will be available for autographs!

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, non-sports cards and comics 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 or comics. (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 and comics 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.
