About Us & Authenticity

About Us & Authenticity was launched in 1999 and is still owned and operated by former Upper Deck Authenticated Product Manager Theo Chen, one of the most successful in person autograph collectors AND modern sports autograph experts in the world. Many of the autographs on this site are from his personal collection, which he started in the late 1980s. He worked for Beckett Media for almost 10 years prior to joining UDA in 1998, and has written nearly 200 published columns and feature stories about autographs, sports cards and collectibles for Beckett Publications and Junior Baseball Magazine over the years. He has been quoted by the New York Times among many newspapers and other publications. He was the top rated Autographs Expert on (now defunct).

Many competitors sell fake autographs, especially on Amazon (which doesn't care about authenticity). Authenticity is my #1 concern. I stake my reputation on every autograph I sell. Every autograph you see here was obtained 1) in person by me or one of my representatives; 2) at a paid signing by a company such as Creative, Mounted, Schwartz, Steiner, TriStar or UDA; or 3) purchased from a trusted source that was extensively scrutinized. Many of the autographs offered here are from my personal collection. I won't sell any autographed item unless I am certain of authenticity!

A written certificate of authenticity is provided with each autographed collectible, as required by California Civil Code 1739.7 (effective 1/1/18). All autographs are guaranteed authentic for LIFE. Each autographed item is accompanied by a Certificate of Authenticity (COA) from and/or the company that authenticated, obtained or witnessed the signature.

Leaf Cut Signature and other certified autographs encased/slabbed with authentication labels OR with authenticity message printed by the card manufacturer do NOT come with COAs.

If you provide a written opinion from the celebrity's agent, estate or team that your autographed item is not authentic, I will provide a full refund. However, opinions from third party authenticator Global Authentics are NOT ACCEPTABLE for refund. partners with James Spence Authentication (JSA) for customers who desire third party authentication.
