Our Founder

iGuide is the brainchild of Jon R. Warren and was founded in 1999. This is not Warren’s first foray into providing pricing information to collectors. He is an internationally recognized antiques and collectibles expert, authoring numerous price guides, including Wizard: The Guide to Comics, The Official Price Guide to Paperback Books, Warren’s Movie Poster Price Guide, and many others. He was the senior price guide editor for Wizard Magazine, Toyfare Magazine, and Inquest magazine from 1993 to 2003. Prior to that, he was the senior editor of The Overstreet Update, a market research guide for collectors of rare comic books. He was the Vice President of Market Research for an 8-million dollar venture capital funded website,, in 2000 and 2001 (it died in the dotcom crash). He has worked as a consultant for Heritage Auction Galleries of Dallas, TX and provided certified appraisal services for many great collections, including the Movie Memorabilia Collection of Michael Wayne, son of John Wayne.

Warren founded iGuide because, “The internet has lacked a free site that allows collectors, appraisers and executors to appraise without any fees or subriptions whatsoever. Our goal is to provide appraisal and identification information for just about everything of value! If it's a tangible asset, we want to be able to tell you what it is worth."

Jon has had the collecting passion since childhood. At age 15, he owned a rare stamp business, selling rare US commemoratives to collectors world-wide under the business name "Rarities, Inc." Collectors purchased thousands of dollars of rare stamps through the mail from Rarities, Inc. never knowing they were dealing with a teenager. Jon opened his first shop at age 19 and began travelling the road in search of artifacts at age 17. He has many great road finds, including one-of-a-kind, only known copies or rare Delta Blues records by Son House and Charlie Patton, world famous finds of rare movie posters (The Royal Theater Collection), an outstanding find of rare rock and roll concert posters, and many others. He is an authentic "American Picker."

Jon graduated summa cum laude from Bryan College with a degree in Business Administration: Informational Management, and magna cum laude with a degree in Computer Science.

Jon is a member of The Project Management Institute and The American Society of Appraisers.

Jon is now president of 2nd Markets Corporation, owner of iGuide and the I Collect network of collector sites. He can be reached at
