Title say's it all, how much do they go for on average if at all, I know back in the day there were next to none of them out there.
I know he used to trade them for anyone's head. I'd say it has no reason to be anything different than chickeneers, so whatever that's worth
That may be so, but I have not been seeing any of heads floating around so iI suspect there is still not many out there. He didnt exactly advertise that he was trading them at will, he just waited for people to ask.
