25 Pfennig

Geisa is a small town in the Rhön region, and like hundreds of similarly sized German municipalities, it issued its own emergency currency — Notgeld — during the inflationary chaos of the early Weimar years when small-denomination coinage had all but vanished from circulation. J. Adolf Schwarz of Lindenberg im Allgäu was a prolific Notgeld printer who supplied dozens of Thuringian and Bavarian municipalities during this period, running what amounted to a cottage industry in local emergency issues.

The DeNG reference distinguishes at least three varieties within this issue, suggesting multiple print runs or color variants — collectors should verify the specific sub-type against the 1/2#413 series breakdown before cataloging.
