10 Pfennig - Karlstadt

Karlstadt am Main issued this notgeld piece in 1917 as the German imperial war economy stripped municipal circulation of nearly all base metal coinage. Zinc was the compromise material — abundant enough to strike, but notoriously prone to corrosion, which explains why uncorroded survivors are harder to find than the mintage might suggest. The nickel-plated variant was almost certainly a production experiment rather than a planned issue, as Funck documents it as a secondary variety rather than an independent emission.
