For more than 100 years, sports fans have been collecting autographs of their favorite players. It's a tradition, and pastime, as old as the game itself.

Today, thanks to outlets such as Tri-Star, Upper Deck Authenticated, Mounted Memories, Steiner, and MLB Authenticated, autograph collecting has become a far less daunting task. These companies are also represented by the pieces you'll see listed in this section along with holograms authenticating the signature.
