1 Pfennig Kaufmännischer Verein Allendorf-Sooden

Allendorf an der Werra and the neighboring salt-works town of Sooden were small communities in Hesse-Nassau whose wartime Kleingeldersatz notes were issued not by a municipal authority but by a local merchants' association — the Kaufmännischer Verein. This was not unusual for 1917–1918 Germany, when the disappearance of low-denomination coinage forced civic and commercial organizations of almost any standing to print their own fractional substitutes.

The Tieste reference places this within the documented Notgeld corpus, but merchants' association issues from small towns in this region were typically printed in short runs and redeemed locally, meaning survivors are genuinely uncommon despite their modest face value.
