100 Kronen

By 1922, the Oesterreichisch-ungarische Bank was issuing currency for a state that no longer existed. The Austro-Hungarian Empire had dissolved in 1918, and Austria — now a rump republic — continued using the old imperial bank as its note-issuing authority until the new Oesterreichische Nationalbank was established in 1923. This 100 Kronen was printed during that awkward interregnum, nominally backed by an institution whose political reason for existence had already evaporated.

Hyperinflation rendered the entire Kronen series worthless almost immediately. The 1924 conversion to Schilling was set at 10,000 Kronen to 1 Schilling, which tells you everything about what circulation did to the denomination's purchasing power.
