10 Heller Herzogenburg

Herzogenburg is a small market town in Lower Austria, and its notgeld issues — including this 10 Heller — were products of the town's own print shop rather than any banking institution. The Buchdruckerei Herzogenburg printed and issued its own emergency currency, which was entirely common practice in Austria during the severe coin shortage of 1920–1921, when even fractional metal coinage had effectively vanished from everyday commerce.

The Jaksch reference suffix "IIIb" indicates a subvariety within the series, suggesting at least minor typographic or paper distinctions between printings — worth checking against a verified example before cataloging.
