Those are more rare than many of the items in this thread. They seem to go for a couple hundred dollars.
The Dragon Archive CD? Really? Didn't TSR make a few gazillion of those? I have one I bought at Gencon the year it was released, and they didn't seem to be all that scarce. You can never tell...
back in my gaming days, I bought practically everything that TSR released over several years, and I ended up with a variety of oddball stuff. Sadly, over the years when I wasn't gaming anymore, I ended losing most of my collection (lost, damaged, tossed out because it was too much hassle to move to another town). Looking through what's left, I still have a few oddities like "Swords and Spells" (the mass combat game for OD&D, I think), some of those random map and encounters that TSR put out in the 80s, and some of those "The Art of XXX" books. I picked up the three "What's New?" collection books somewhere along the way, although, sadly, I seem to have lost the "Fineous Fingers" collection somehow
Although I've lost most of them, I still have the first 36 issues of Dungeon, and some early issues of Dragon. For non-TSR stuff, I have "The First Fantasy Campaign" by Dave Arneson, and "Heroic Expeditions" by Judges Guild (why the hell did I ever buy
that....)
