I may have figured out the first chip. Anyone have any info or comments on the rest? Thanks.

1. "Silver Slipper"
Currency is Rupees? There was a Silver Slipper casino in Sri Lanka that was torched after the 1999 Presidential Elections. Anyone know if it was rebuilt? There's one listed in the capital, Colombo, same one?

2. "Casino 28"
3. "Dorado Beach"
4. "W.A. INC. Dickinson, ND"
5. "Plains Oak Manor, FGO, ND"
6. "Bell Atlantic International"
