300 Gulden

The 300 Gulden denomination was the highest value note in the Austrian imperial emergency emission of 1848 — a year of revolution across Europe that forced the Habsburg treasury into a rapid expansion of paper currency to cover military and administrative costs. The k.k. Staats-Central-Cassa issues of that year were state treasury instruments rather than banknotes in the conventional sense, bypassing the Nationalbank entirely.

At this face value, the note would have circulated almost exclusively in wholesale mercantile and government payment channels. Surviving examples are rare simply because high-denomination paper was redeemed quickly when stability returned.
