Prices are up and down on all casino collectibles. We bought most of our stuff 10-15-ish years ago...when prices were much higher. At that time the casino mini-decanters were running around $65-$95, depending on which casino. I'm not sure what the brothel decanters were selling for.

Personally, my measure is always "do I love it enough to pay $xxx for it? Will I be totally bummed if I see one sell next week for half of $xxx?
