20 Heller Straß

Austrian Notgeld of this type emerged from a specific administrative crisis: the postwar collapse of small-denomination coinage left rural municipalities scrambling to facilitate everyday transactions. Marktgemeinde Straß, a small market town in Styria, issued these Heller notes under emergency provisions that briefly empowered local authorities to fill the gap left by Vienna's inability to supply sufficient fractional currency in 1920.

Styrian municipal Notgeld was typically printed in very small runs, often by local job printers, and redeemed quickly once coinage supplies normalized — meaning survival rates are low and documentation thin.
