30 Heller Oeblarn

Oeblarn is a small farming village in the Enns Valley of Styria, and like hundreds of similarly sized Austrian municipalities, it issued its own small-denomination Notgeld in the early 1920s to compensate for the chronic shortage of coins that had been melting out of circulation since the war. The 30 Heller was among the most common denominations in these local emergency issues — useful for everyday transactions that postwar coinage simply couldn't support.

The Jaksch reference suffix "IIa" indicates a recognized variety within the series, likely a paper or printing distinction rather than a date change.
