BUT most comics published after a certain point aren't worth much to begin with, and binding them makes them more desirable to many. When I got rid of most of my collection, I can say without a doubt, I sold the vast majority of my binds for significantly more than I'd have gotten trying to sell the issues as a lot. So take from that what you will.
