I am debating about selling all of my rpg material I have collected over the past twenty years or so. Don't have time for it anymore and just don't see myself ever getting back into to it.
My question is, is there a reliable site to determine the value of any of it? Like my old Dark Sun cloth map for example.

When I opened my Pathfinder Adventure Card Game box, I noticed that one of the Blessing of Iomedae cards was damaged on the back. Is there a way that I can get it replaced?

Thank You, and great job on an excellent product!
