Each product is authenticated under the auspices of the PGA TOUR and carries a uniquely numbered hologram to ensure authenticity. A PGA TOUR official witnesses the balls being removed from the water around the 17th hole. The official and his assistant adhere a hologram sticker to each ball. The balls are transferred to Tokens and when they are transformed into an item, the Authentication Director at Tokens & Icons affixes a secure hologram to it. This allows you to trace the history of your item by visiting PGA TOUR Authentication.
