I think shows like Antiques Road Show and the big ebay stories lead everyone to believe that old=treasure.
I have all these 1942 dentistry books to unload, but i am afraid to just donate them. In the back of my mind I feel they must be worth something. As just an example.
BLR, i think you are right, and we do have internal instructions to pick things up and take them along. Stoopid thumbs.
