An authentication expert from Global Authentics will be on-site to authenticate your autographed items.

Please make arrangements to drop off anything you wish to be reviewed by close of business ONE DAY prior to event.  You will be able to pick up your items as soon as the day following the event. 
Items must be submitted before the event. 
No Walk-ins during Authentication events!

An authentication representative from Global Authentics will be ON-SITE at Valley Sports Cards, Memorabilia, & Picture Framing to authenticate your autographed items.  There is no limit on the amount of items and you may submit virtually any signature: sports, entertainment, historical, political, authors, investors, dignitaries, etc. 

Autograph certification has become a major component in collecting. An autograph verified by a trusted expert instills confidence in buyers and provides immediate value to an item on the open market. Simply put, certification removes any uncertainty when dealing with autographed memorabilia.  Items deemed authentic will receive a Global Authentics tamper evident label, be assigned a unique certification number, and issued a corresponding Certificate of Authenticity (COA). Certificate numbers are then added to the Global database and can be verified online using CertCheck.

If you have any questions, please don't hesitate to ask.  Thank you!
