The 2013 National Sports Collectors Convention is the biggest event of the year when it comes to sports cards and memorabilia. The 2013 National takes place at Chicago's Donald E. Stephens Convention Center from Wednesday, July 31 through Sunday, August 4. This is the event's 34th year.
About 600 dealers will be on hand, giving collectors a massive amount of cards and memorabilia to look at and purchase. About 50 corporate booths will also be set up, including major card manufacturers. The National is always a great place to find exclusive cards not available anywhere else. For many, the highlight will be meeting past and present athletes during autograph signings and photo opportunities.
