GAI authentication is the verification applied by Global Authentics, LLC, of any autographed sports, entertainment and historical memorabilia. This authentication is used by Internet commercial sites such as eBay and consumers worldwide. Authentication experts use art security detection technology and expert analysis to confirm signatures and apply the Global Authentics label to the memorabilia.
The physical analysis of memorabilia items include a side-by-side comparison of an authentic signature, an ink and medium analysis, close inspection of the autograph structure, and an overall object evaluation. Once the signature passes the test, a tamper-evident label with a unique serial number is applied to the item along with a Letter of Authenticity containing full details about the item and the results of the examination. If the item is found to be a inauthentic, Global Authentics provides a letter of explanation for an additional fee.
The combined Global Authentic expert staff provides over 100 years of autograph authentication service experience, and the GAI authentication seal is considered to be the standard for autograph authentication. Global Authentics, LLC, is a Pre-Certified Authenticator for eBay and offers its Digital Autograph Review Service for consumers to receive GAI authentication on any item in question for a fee.
