50 Heller Sonnberg

Sonnberg is a small municipality in Salzburg province, and this 50 Heller note is a product of the Austrian Notgeld wave that swept rural communities between 1919 and 1921. The central government's inability to keep small-denomination coinage in circulation — drained away by wartime metal requisitions and postwar hoarding — forced even minor parishes to print their own emergency fractional currency. Zaunrith was a Salzburg-based printer that handled a number of these regional issues, which accounts for the consistent production quality across several Salzburg-area Notgeld types.

The Heller denomination itself was already being phased out nationally by 1920, which gave notes like this an inherently short useful life.
