My mother and I recently purchased these chips. All are in excellent condition with no holes drilled in them. The Patio and First Council (local Native American casino) chips have the same printing on both sides. The Desert Spa is printed on one side only. The three Moulin Rouge are mounted in metal cases with an open face and a loop on top to allow attaching to something like a necklace. Two gold tone and one silvertone. I have learned from that the Desert Spa is likely from 1947 and The Patio from 1954. I do not know anything else about chips. Can anyone help me with values (approx is fine), age and explain why the Moulin Rouge are in metal cases?
