5 Pfennig - Driesen Brandenburg

Driesen — today Drezdenko, in what is now western Poland — issued emergency coinage during the First World War when the imperial government's requisitioning of copper and nickel left municipalities scrambling to keep small change in circulation. These Stadtnotmünzen were produced under local magistrate authority, a legal grey area that Berlin tolerated out of necessity rather than endorsement. Iron was the de facto fallback material by 1917–18, cheap enough to strike but corrosive enough that survivors in collectible condition are genuinely uncommon.
