10 Heller Wartberg ob der Aist

Wartberg ob der Aist is a small market town in Upper Austria, and like hundreds of other Austrian municipalities it issued emergency paper money — Notgeld — during and after the First World War to compensate for the near-total disappearance of metallic coinage from everyday commerce. The 10 Heller denomination was the workhorse of local Notgeld, intended for genuine small-change transactions rather than collector speculation, which became a problem for later series.

The Jaksc/Pick reference places this in the documented Austrian local issues corpus, but Wartberg's output was modest. Notes from minor Upper Austrian communes in this denomination frequently show heavy circulation wear — they were actually used.
