Acquiring your favourite autographed collectable can be one of the most exciting investments you make as long as it is authentic. At CollectibleXchange, the integrity of each of their hand-signed collectables is paramount. In order to guarantee the authenticity of your hand-signed sports collectable, CollectibleXchange representatives witness athlete signings and authentication sessions. Most items will be authenticated by one of the industry's top authentication companies, such as Upper Deck, JSA, PSA, Tri-Star, Beckett, Steiner and others. If an item was witnessed by CollectibleXchange staff, the item will receive a tamper-proof numbered and QR-coded hologram.
