10 Pfennig - Frankfurt an der Oder

Frankfurt an der Oder issued notgeld coinage in 1919 as Germany's postwar coin shortage bit hard — the Imperial minting infrastructure had collapsed, metal was scarce, and municipal authorities across the country were forced to produce their own emergency currency to keep local commerce moving. Iron was a practical if unglamorous choice, already familiar from wartime Kriegsmünzen. The Funck reference places this squarely within the documented Brandenburg municipal issues, a well-catalogued series that nonetheless sees individual pieces disappear from the market for years at a stretch.
