First... wow- looks like I was mildly clueless as to my good fortunes!
Anyhow, I make no pretenses about being a wizened old collector. I'm still in the learning process here. So, here's a sales related question for y'all:
When you are trading comics with someone, at what value do you trade the books? I know when selling comics, you usually look at the FMV or at least the typical % off the OSPG for books of that title and grade. Does it work the same with trades? Stupid question perhaps, but I'd still be stupid without an answer if I didn't ask.
