My complete adult career has been immersed in pop culture!

I appeared for 10 seasons as an on-air appraiser of sports, entertainment, pop culture & general collectibles on the PBS seriesAntiques Roadshow.

Employed at CBS TV, Universal Studios & ABC TV, gave me a strong foundation in the entertainment world, working my way up as a television executive for Dramatic Series Development, creating series ideas with writers, directors & producers. I retain some of my longtime contacts which helped result in the handling of Sylvester Stallone’s movie memorabilia collection, “STALLONE – THE AUCTION.”

As early as the late 1960s I began buying, playing, trading & selling “old” guitars before the business eventually blossomed into the “vintage guitar” business. This groundwork plus my auction background gave me the opportunity to become Consignment Director for Heritage Auctions Vintage Guitar department for 10 years.

Collecting sports memorabilia since my first card show in 1979 had grown to such a passion that I switched into the sports memorabilia business and have since coupled sports, entertainment & musical instruments into my expertise. Was brought national prominence in the mid-1980s when I purchased the Alexander Cartwright collection, the founder of baseball. Started Mike Gutierrez Actions & ran it successfully for 10 years. Along the way appraised some important collections & authenticated autographs for PSA & JSA. Joined Heritage Auctions, where I have brought some auction highlights in other areas as: coins, jewelry, movie posters, silver, watches, animation art & wine since 2006.

With my solid background in entertainment, sports memorabilia, musical instruments, auctions, consulting & authentication, I can assist you with confidence in your consultation & appraisal!
