75 Heller Oberalm

Austrian municipal notgeld of this scale presents an almost comically practical problem: at 47 × 37 mm, the thing is barely larger than a postage stamp, a consequence of wartime and postwar paper shortages that forced municipalities to print emergency currency at whatever size the available stock allowed. Oberalm, a small village in Salzburg province, issued its notgeld under the same collapse of central monetary authority that pushed hundreds of Austrian communes to print their own fractional currency between 1919 and 1921.

The 75-Heller denomination is among the more unusual fractional values — most communes defaulted to round figures.
