They aren't rare at all. I have 3 of them for sale right now on my web site for $15 each. Years ago, they were offered for sale by CC>CC for face value. If anyone would like to purchase 1 or all 3 just e-mail me or click on link below and enter alphabetical listing of "House Chips". I just sold 2 more at the Palms show. There is no $1 chip, but there are some $25 chips.
