90 Heller

Austrian Notgeld of the early 1920s emerged from a severe small-change shortage that followed the collapse of the Habsburg monetary system. Communes across Tyrol, Styria, and Upper Austria filled the gap by issuing their own emergency pfennig and heller denominations, often in small print runs intended for purely local use. Hart was one of hundreds of villages that did exactly this — which paradoxically makes individual commune issues harder to track than the larger municipal series.

The 90-heller denomination is an odd one, chosen to satisfy specific transactional needs rather than any standardized breakdown. Franz Erssl's signature as issuing authority locates responsibility at the commune level, with no banking intermediary involved.
