I used to have a lot of luck running local ads saying I buy toys. One time an elderly couple called and told me they had some really old games. I got there and the stuff was pretty common. Rook and Contak card games. I asked them if they had anything else. They said they had some trucks in the attic, but that they were not that old, only from the 60's. I bought nearly a dozen Tonka and Nylint trucks for $20.
