About Main Line Autographs' Pittsburgh Show
Main Line Autographs has been a staple of the autograph collecting community in Pennsylvania since the early 1980s. With more than 100,000 different autographed items displayed at every show and convention, Main Line Autographs has built an impressive inventory of signed memorabilia that is guaranteed authentic for life. What started as a local business has grown into a well-known, nationally recognized leader in autographed items, with an annual trade show hosted at the Monroeville Convention Center.
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:
- Create a CGC account here. All it takes is a free account to submit, and paid members get additional discounts and benefits.
- Go to the online submission form for cards. (For JSA memorabilia submissions, just bring your item to the show.)
- 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.
- Complete the submission form and print the packing slips.
- Keep your collectibles safe and secure until you drop off your submission (including the packing slip) with a representative.
- Go to the Express Drop-off sign to finalize your submission.
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.
All submissions will be transported to CGC’s headquarters in Sarasota, Florida, for authentication, grading, and encapsulation.
