Łódź Ghetto mark
Łódź Ghetto mark (German: Mark, Polish: Marka getta łódzkiego) was a surrogate currency that circulated in the Łódź Ghetto in 1940—1944 until the Ghetto was liquidated in August 1944. It was divided into 100 pfennig (German: pfennig). The notes had no value outside the Ghetto, and could not be exchanged into other currencies.
