15 Pfennig - Mainburg

Mainburg issued this zinc notgeld piece in 1917 as wartime metal requisitions stripped German municipalities of copper and nickel — the standard coinage metals — leaving towns to improvise with whatever the central authorities hadn't yet claimed. Zinc was deeply unpopular for small denomination strikes: it corrodes aggressively in circulation, and surviving examples with intact surfaces are considerably less common than raw survival numbers suggest.
