Honestly, depending on how "vintage" they are and what kind of condition they are in, the Playboys may be worth some money. There are a lot of collectors of those, and, well, they do have good articles and interviews.
What type of comic books?? I have most of the comic book my sis and I bought when we were young!! Mainly Archie, Richie Rich, Wendy-types like that. I even have some #1!! Also Mad Magazines and Cracked Magazines from the early 70's. I couldn't bear to part with them so most are in a box in the attic except for the #1-#10 which I keep in craft room.
