20 Heller

Göttweig Abbey, a Benedictine house on a hill above the Danube near Krems, issued this Heller note as part of Austria's widespread Notgeld phenomenon — the emergency small-change currency that exploded after the First World War when coin metal vanished and the central government couldn't keep up. By 1920, thousands of Austrian municipalities, businesses, and institutions were printing their own. The Kellerstube reference is specific: this was issued by the abbey's own wine cellar establishment, not the monastic administration broadly.

Signed by P. Ludwig Koller, a monk rather than a banker. That detail alone separates this from the municipal issues.
