10 Pfennig - Aschaffenburg

Aschaffenburg's 1917 iron notgeld issue belongs to the first wave of German municipal emergency coinage, driven by the wartime hoarding of copper and nickel that had stripped small-denomination Reichscoinage from everyday circulation by mid-1916. Cities were effectively left to solve their own small-change crisis. Iron was the compromise — abundant, strategically unimportant for these quantities, but prone to corrosion, which accounts for the difficulty in finding problem-free survivors today.
