That is crazy...I have two of them. Bought one in a shop and one on eBay...both under $20 and from different sides of the country. They were as far as I can tell pretty widely distributed. I would dispute the 500 made...seems to be way too many of them kicking around for that. Defintely a neat and historic bottle, but I would not call them rare by any stretch. Heck of an expensive mold to just run 500 bottles.
