James Spence Authentication (JSA), Booth # 1245

JSA Story

“Autograph collecting is a Spence family tradition that has been passed down through four generations. Following his grandfather and father, founder James Spence Jr. started out as an avid collector of sports memorabilia. Collecting autographs turned into a business as he traveled across the country attending major trade shows buying and selling memorabilia. His passion for autographs led him to extensive research and compiling an autograph exemplar library, which is second to none in the autograph industry today. James, Jr's reputation within the autograph world caught the attention of major auction houses across the country, which then employed his authentication services for their upcoming auctions. Thirty years later James Spence has built a worldwide reputation as the premier autograph authenticator in the world.

JSA has accumulated an impressive database of known signature examples, which are used by autograph authenticators to accurately assess the thousands of autographs seen daily. The exemplar file is the most important tool JSA utilizes when authenticating any autograph. Submitted signatures can be compared to known authentic and forged examples, including non-malicious attempts. JSA experts regularly visit auction houses, attend trade shows/conventions and constantly research the veracity of autographs of sports figures, celebrities, entertainers, politicians and historical figures. Their strong research and exposure to this volume of autographs allows them to continually add to their growing autograph exemplar database, unparalleled in the autograph industry.


Any item backed by James Spence Authentication is instantly marketable, enhancing its maximized value and making the item easier to sell to a potential buyer. Certified items are given a unique alpha-numeric code and documented into a database that can be verified by visiting SpenceLOA.com.

Is there a pre-show registration? Will you be taking all walk-ups?

There is no pre-show registration and walk ups are always welcome. We do encourage anyone that has any questions about their autograph items before hand to contact us via our website or social media (@jsaloa) for further inquiry on authentication and our fees.


Authentication fees are based on the value of the celebrity or athlete's signature, what type of item it is on and how many people signed that specific item.
