90 Heller Obernberg bei Gries am Brenner

Obernberg am Brenner is a small Tyrolean village sitting almost exactly on the main Alpine transit route between Innsbruck and the Brenner Pass. This 90 Heller note is a Notgeld issue, one of thousands of emergency municipal scrip pieces produced across Austria between 1919 and 1921 when small-denomination coinage had essentially vanished from circulation following the collapse of the Habsburg monetary system.

The 90 Heller denomination is distinctly odd — a deliberate collector-bait value, common among the so-called "Seriennotgeld" wave, where municipalities issued unusual face values knowing philatelists and notgeld collectors would absorb them without ever spending them.
