The obvious place is ebay. If you don't want to lose them for too cheap a price, you can put a reserve on them, but if they are truly valueable, the other bottle collectors on there will bid them up quickly when you put a low starting price on them. It's kind of a double edged sword. Put them on there for a low price and take a chance (this works 8 out of ten times I would say), or put a reserve on there and have ebay steal your $. At least with a low starting bid ebay won't be able to steal your money as easily. I am beginning to think with all of the fees that ebay charges (now they own Paypal too, so they can gouge you more) that the local swap meet might even be a better deal for the lower end stuff that just doesn't seem to move to easily. All in all though, ebay still holds the #1 spot and has the most viewers from all over the world. There is nothing that compares. It is like the "Microsoft" of the auction world. Good luck!
