I have paid up to $25 for a Monaco Monte Carlo bracelet with 6 jetons & tokens. Individually, I think about $10 max. They are dirt common. The ones with the rounded, raised borders are not Monte Carlo. They are of unknown origin. Since they have a tiny "C", "E", "P" in the corners of the filligree, I have speculated on Casino Elysee Palace in Vichy, France. John Benedict says, "No way." So, we go along with "unknown."
