This was a surprise to me. It appears to be a Paul-son metal inlay chip from the 1970's, similar to those made for a number of Nevada Casinos. I have a 100Fr and 2500Fr Paul-son metal inlay with H&C molds and no casino markings. This one is very similar but has the Casino Monte Carlo mold! Has anyone seen others from this series? Is it possible that this chip was made by someone else (in Europe, maybe)?

Got this from Doug Saito.
