PSA/DNA is the leading authentication service for championship rings, trophies and awards providing a much needed service in the hobby. PSA/DNA uses the same state of the art technology for autographs to protect your rings, trophies, and awards. Once an item is deemed genuine, the item is marked with invisible DNA-laced ink – naked to the eye but verifiable through a specially calibrated infrared laser. In addition, a Letter of Authenticity (LOA) containing a photo of your item and specific details on the analysis will accompany your item. With our unique alphanumeric number, any interested party can verify authenticity online even as items change hands time after time.
