When was ghetto money produced in the Holocaust?

Answer 1

It varied from one ghetto to another. Usually, the Nazis did not like the people in ghettos to have money that was valid outside the ghetto, as they regarded money as a potential source of power. The best known "ghetto money" was that produced by the Lodz ghetto and by Terezin (Theresienstadt). On entering the Lodz Ghetto, Jews had to swap their ordinary currency for ghetto currency, that could not be used outside the ghetto.
