Piffy wrote in New collector's ADnD finds:Thanks for having me. That's more or less the conclusion I came to, so it's nice to have it verified. My local used bookstore just got 2 collections in and I've been picking through it all. Up till now I've mainly just collected Planescape stuff so I've had to do a lot research. That lot also included a first printing DMG inscribed by Gygax, but they priced that at $600 which seems excessive. The one other interesting item was a first edition City State of the Invincible Overlord for $75. Seemed more or less complete, with the pink mailing card and all. How good of a price would folks say that is? There's little recent eBay history to go off.
