100.000 Kronen

The 100.000 Kronen was not a denomination that existed in peacetime imagination — it materialized because the Austro-Hungarian monetary system was already disintegrating before the armistice was signed. Wartime spending had driven note circulation from roughly 3 billion Kronen in 1914 to over 30 billion by late 1918, and the Oesterreichisch-ungarische Bank was printing denominations of a size it would never have contemplated a decade earlier.

The bank itself ceased to function as a unified institution with the collapse of the Habsburg state in November 1918. Successor states — Austria, Czechoslovakia, Hungary, Yugoslavia, and others — each stamped or overprinted circulating Kronen notes to claim them as national currency before eventually replacing them entirely. Whether this specific note was stamped or left unmodified depended entirely on where it happened to be when the empire ended.
