So far I have the Year Of The Rabbit chips From...

Bally's
Bellagio
Caesars Palace
Harrah's
Imperial Palace
M Resort
MGM Grand
Palace Station
Palms
Rio
Wynn

And I just purchased Paris and Planet Hollywood from David S. via his website marlowcasinochips.com

I've never seen the Venetian or Gold Coast chips for sale and the Palazzo chip only a few times.
