I've had the chip for about 30 years and never really searched the monogram until recently when I was asked if I know it is from Royat.

There is a lot of reference online though, I have not come across anything with the exact monogram pertaining to any casino in Royat (monograms on casino metallics, plastics, MOP or bone; letterheads and any other paper documentation do not always match and could be quite different -- and there are also chips from casinos having two different monograms with one on each side).

Does anyone have any information...?
