In the 'Annees Folles' (The crazy years) of the Charleston etc. We had a small boom of small casino's where there was gambeling. They where, Cercle Prive, which means, private club. So you could not just walk in, you had to be invited and have a godfather who would vouch for you.
Most of them where closed by the end of the 1920s max early 1930s. But some of the casino's survived.
Below you see a scan of a jeton from, we guess, the early 1920s. It is very light, made of bone. Note the spelling Casino de Blankenberghe, it is still the old spelling and French. Althought that now Blankenberge is in the Flemish (Dutch) part of the country, in those day the rich, most of them spoke the fancy French, where going to the coast for their holidays.
Just for your vieuwing pleasure, I try to make a good scan of the other old beauties I have stached away ,it is not easy to get a good scan of the old material.
Kind regards,
