20 Heller Hinterbrühl

Hinterbrühl is a small village in Lower Austria best known, if at all, for the Seegrotte — a flooded gypsum mine that became a Heinkel aircraft factory during the Second World War. In 1920, it was simply a minor municipality scrambling, like hundreds of Austrian communes, to address the acute small-change shortage that followed the collapse of the Habsburg monetary system. The national currency had not yet stabilized, coin metal was being hoarded or had simply vanished from circulation, and local governments were legally permitted to issue their own emergency scrip under postwar Austrian Notgeld provisions.

The Jaksc suffix "Ie" places this within a recognized series variant — collectors should note that Hinterbrühl issues appear in several distinct printings, and the suffix distinctions matter for completeness.
