What is a Sports Memorabilia Mystery Box?

A sports mystery box is an assortment of autographed sports collectibles from current sports stars and legends of the game. Sports fans have the opportunity to add a high-value name like Tom Brady, Patrick Mahomes, Aaron Rodgers and more to their sports memorabilia collection! Each Ultimate Mystery Box is guaranteed to contain autographed sports memorabilia from Hall of Fame players, current stars and legends of the game.

The most popular version of The Ultimate Mystery Box are our football autographed sports memorabilia mystery boxes. These signed football sports memorabilia boxes contain autographs from members of the Pro Football Hall of Fame, legendary players and current NFL stars. The football Ultimate Mystery Boxes feature autographed footballs, signed mini helmets and full size football helmets, autographed jerseys and much more!

Each signature on the signed sports memorabilia is guaranteed to be 100% authentic and comes with a certificate of authenticity (COA) from a reputable third-party company.
