I went to the Roadshow a few years ago right when Captain America First Avenger came out. I figured since the movie was coming out, and with all the hype, that there would be some interest in a nice Captain America 1 comic for the show. So I brought my raw Cap 1 in. The appraiser looked at it with virtually no interest whatsoever. He said he didn't know what it was worth off the top of his head and that I should just look in an Overstreet price guide. I went in with such energy and excitement, and he seemed to have NO passion at all. It wasn't the best experience (with him). They have a lot of appraisers so if you get matched up with a bad one, you're out of luck.
They allow you to bring 2 items. My other item (Indian Clubs) garnered a huge reaction by the other appraiser, and they ended up taking me to the GreenRoom to put makeup on me to do an interview. It was really cool. That appraiser showed huge passion and loved talking to me about the clubs. They started to set us up for the interview, but a producer came by and decided to nix my segment. Bummer.
