Every single item comes with a Certificate of Authenticity from GM Authentic Autographs. Some items may also come with additional authentication through proof photos (when available) or certification from leading TPA's such as Beckett, PSA/DNA or JSA! Location of Signing: Specific signing details available upon request. For any item that is not already James Spence (JSA) Certified, we can. Have that service provided for an additional charge.
