500 Mark Forum-Scheck

Forum Außenhandelsgesellschaft was the East German state's hard-currency retail operation — a mechanism for extracting Western money from citizens who received it from relatives abroad. Holders of Deutschmarks or dollars were compelled, in practice, to convert them into Forum-Schecks at a punishing 1:1 official rate, then spend those cheques exclusively at Intershop outlets. The arrangement gave the GDR access to hard currency it could not earn on its own terms.

The 500-Mark denomination is the highest in the series. A print run of over twelve million copies at this face value implies enormous systemic demand — or at least enormous state optimism about how much Western currency it could intercept.
