Yes Albert, It is like Holland Casino they have the same jetons in each casino. Although there are some LE edtions popping up. Germany has more or less the same system only there they are the same for the same group. Like West Deutsche Spielbanken's jetons from Aachen you can use in their Berlin casino. But as I posted a while back, the German ones are making new jetons with the name/city of the casino on it.
