10 Heller St. Nikola an der Donau

St. Nikola an der Donau sits at the narrowest point of the Strudengau, the stretch of the Danube historically feared by boatmen for its whirlpools and rapids — "Strudel" being the source of both the regional name and genuine navigational peril before 19th-century blasting works widened the channel. The Marktgemeinde issued this Heller note in 1920 as part of the Austrian Notgeld wave, when postwar currency shortages forced hundreds of small municipalities to print their own emergency scrip.

Hiebl in nearby Grein was a logical choice — a local press serving local need. The official stamp substitutes for the security infrastructure no village printer could replicate.
