50 Heller Kallham

Kallham is a small market commune in Upper Austria, and like hundreds of similarly sized municipalities, it issued Notgeld during the severe coin shortage that gripped Austria from roughly 1920 onward. These emergency issues were a local administrative decision, not a central banking one — the commune effectively printed its own small change because none was available through normal channels.

The JPR prefix in the Jaksch reference system designates Austrian rural municipal issues, a category notorious for short print runs and poor archival survival. The 50 Heller denomination was the workhorse of Austrian communal Notgeld.
