50 Heller St. Martin im Mühlkreis

Austrian Notgeld at the 50 Heller denomination was churned out by hundreds of small municipalities between 1919 and 1921, partly from genuine small-coin shortages and partly because the collector market had made these local emergency issues briefly profitable to produce. St. Martin im Mühlkreis, a small market town in Upper Austria's Mühlviertel, participated in this second wave — by 1920 the acute shortage justification had largely passed, and many communes were printing primarily to sell to collectors rather than to meet any real circulation need.

Paper quality and print longevity vary considerably across the Upper Austrian municipal issues of this period, with some showing significant foxing from low-grade wartime paper stocks.
