20 Heller Hagenberg

Hagenberg is a small market town in Upper Austria, and this 20 Heller note is a product of the Notgeld emergency currency wave that swept Austrian municipalities between 1919 and 1921. With the postwar collapse of the Austro-Hungarian monetary system leaving small coins effectively unavailable, thousands of communities — including villages with no meaningful financial infrastructure — were authorized to print their own fractional paper. Hagenberg's issue was produced by Jos. Feichtingers Erben, a Linz printing house responsible for a substantial number of Upper Austrian municipal Notgeld series during this period.

Sepp Wiltschko's design credit is worth noting — local artist involvement was common in the more collectable "Künstler-Notgeld" issues, and the Jaksch/Pick reference JPR0330a confirms this as the lower of at least two denominations in the series, signed by municipal official Johann Stöger.
