50 Heller Wien

Vienna's municipal emergency money — Notgeld — filled a genuine void left by the collapse of the Austro-Hungarian monetary system after November 1918. The central government could not produce small-denomination coinage fast enough to meet demand, so individual cities, towns, and even private businesses across the former empire issued their own scrip. Wien's series, authorized under the Stadtgemeinde, was among the more systematically produced, with Paul Gerin handling the printing from his press in Wien II., the Leopoldstadt district.

Gerin was a well-established Viennese commercial printer, not a security specialist, which is worth noting — these were never intended as long-term currency.
