2 Pfennig

Passau issued small-denomination Notgeld during the First World War emergency, when coin shortages created a vacuum that municipalities across Germany rushed to fill with their own paper substitutes. The City of Passau's 2 Pfennig notes rank among the smallest format emergency currency produced by any German issuing authority during this period — the square cut was a practical response to paper rationing, not a design choice.

At this denomination, the notes were almost certainly used for local retail transactions, primarily to make change, and most were discarded rather than redeemed once the shortage eased.
