Here are two Borland 'registered' chips I hadn't seen before. Both are from the Janice O'Neal collection.

The 50c was made for the Kalispell Eagles Aerie in Montana. Surprisingly, this club is still open, and still licensed for gaming! Wonder if these half dollars are still on the tables?

The black chip appears to be a host-chip from the Dunes. I have no idea who Arthur Fordonski was, and I could just be a player who like the Dunes in Las Vegas (or some other Dunes?). Or maybe BillB DID make a ROMAN chip for a Nevada casino?
