I have recently learned that the Wind Creek casinos (the former Crystal and Seaport Casinos) have 1 Florin and 5 Florin chips. I would love to get a few of each. I believe they are only available to locals (maybe anyone who pays in florins?), but you can buy them from players who are using them. A bit tougher to get than most chips, but probably not super hard.
I am also still looking for a $2.50 Xanadu chip.
If anyone if in Aruba or going soon and is willing to help me out, please send me a private message. Thank you!
