1 Pfennig

Neumühlen-Dietrichsdorf was a small industrial municipality on the western outskirts of Kiel, later absorbed into the city proper in 1924. Like hundreds of German communes during the acute small-change shortage of 1917–1921, it issued its own Kleingeldersatz — emergency fractional currency — because Reichsbank coins had vanished from circulation almost entirely, hoarded or melted down. A one-pfennig denomination is among the lowest values produced in the entire Notgeld period, reflecting just how completely the small-coin supply had collapsed.
