A system for tracking an authenticated item is provided. The system includes an authentication device affixed to the item. An item registration system receives authentication device data from the authentication device and associated item data and stores the authentication device data and the associated item data. An owner registration system receives owner registration data after a buyer has acquired the item. A buyer verification system receives the authentication device data, the associated item data and the owner registration data and stores buyer verified data if the associated item data correlates to the owner registration data, such as if the external tag number or event data entered by the owner matches external tag number or event data for the item.
