Larry,

the red sign in the inlay of the first chip is the sign of the "Austrian Casinos" group.
The Oasis is in Jericho, Palestine. It was opend 1998 and not closed.
Please look at http://caigkn.caigroup.at/pls/gknweb/www.show_operations_flash and click on "Asia".
I do not know if the second chip is from the same casino.

Many greetings from Germany,
Bjoern
