Does anyone have info on what these chips on E-Bay are? They appear to have the logos (not just the names) from "GRAND-STARDUST-SANDS-CAESARS-CIRCUS- ALLADIN-DUNES-RIVIERA" casinos on the mold. Do you think that the casinos could have licensed their logos for use for a set like this, or do you think that they were made without permission?

Also, any ideas on their 'value'?

Thanks!
