Tricky question for me. Because it wouldn't just be buying a set in my mind. It would be buying the rights to all things The Hitching Post. That would mean someone would need to buy all three Hitching Post sets, five tables, three boxes, plus all the accoutrements like seating plaques, dealer buttons, etc.
Once you add all of that up the cost number is pretty prohibitively high....then you try to think how much extra it would take before I WANTED to sell it?
The easy answer is as long as I'm not desperate for money more than anyone would ever pay me.
