HK$100 denomination.. This currency and these jetons were used from 1962 to 2001 in old Macau. I was there in the 1970's and played at the Lisboa (the round cylinder) where nobody spoke English! The big US casinos weren't built yet in Macau.

At the time, I was hard to get a seat at a table game so it was routine to stand behind a seated player and bet along with him. The biggest bet called the plays on that hand, even if he was standing .

A 45 mm jeton in translucent yellow with a violet stripe. S.T.D.M. stood for S.T.D.M. Sociedade de Turismo e Diversões de Macau in Portugese as Macau was originally a Portugese colony. Made, I believe, by French company Bourgogne et Grasset.

100HK$ is currently about US$13.

Reverse has lettering in Chinese characters.
