10 Pfennig - Magdeburg

Magdeburg's 1921 iron notgeld issues were part of a broader municipal coinage wave that swept German cities as the Reichsbank struggled to keep low-denomination metal currency in circulation. Iron was a deliberate and pragmatic choice — zinc and aluminum had been overused during wartime emergency coinage, and iron at least carried some scrap deterrent against hoarding. The Funck reference places this squarely among the documented iron series rather than the more abundant zinc strikes from the same city.
