The Venetian, Las Vegas. Poker Room. Used in one of their tournaments held monthly, I believe but not sure of the schedule. If I am correct, you cant buy the chip, you have to win it for entry to the next level. Maybe someone else will know more detail about it. I do have one extra of the 100. Email me if interested.

There is also a 500.00 version of this chip which I do not have in my collection. If someone else has the 500, maybe they'll post the pic.
