Still popular or have these gone the way of baseball cards?

The reason I ask is because I found a box in my closet with about 30-40 comic books.
None of them Disney

I remember years ago when they had baseball card trading events I would always see a couple of people selling comic books. I think there may even still be a comic book store in my area.

Do they trade comic books in stores? I would like to sell these and if not trade them for Disney ones.
I just don't want to walk in there and have them look at me like I'm crazy

Is there a website for comics that may show the value? I can't imagine these being worth very much if anything.
