Since 1988, Upper Deck has been a pioneer in the autograph authentication process. The company revolutionized the trading card industry by introducing a new technology that improved the overall quality of the card and added a hologram that prevented their cards from being counterfeited. Upper Deck memorabilia goes through a five-step authentication process. First, an Upper Deck Authenticated representative attends every athlete signing and witnesses every autograph that is signed. Next, the UDA representative and the athlete sign off on a record of the autograph session, which is kept by UDA in a permanent file. Third, each piece of autographed memorabilia is affixed with a serial numbered hologram. Next, a certificate of authenticity is issued to every piece of memorabilia. The Upper Deck Certificate of Authenticity is approximately the size of a large greeting card and is printed on glossy card stock. Included on this certificate is a hologram that matches the one affixed to the item. Finally, each piece of UDA autographed memorabilia is packaged with a registration card. When you by an item authenticated by Upper Deck, you have the opportunity to register your purchase with Upper Deck Authenticated. Should you decide to sell that item later, you can provide the new owner with a detailed record of that item’s history.
