10 Mark

Landsberg an der Warthe — now Gorzów Wielkopolski in Poland — was a mid-sized Prussian town whose municipal authority issued notgeld during the paper money chaos of the early Weimar period. This 10 Mark piece comes from Carl Flemming A.G., a Glogau-and-Berlin printing house with a long track record in commercial and official print work, pressed into notgeld production alongside dozens of other regional printers as demand overwhelmed the Reichsbank's capacity.

The embossed stamp is the only security measure — a frank acknowledgment of how little counterfeiting deterrence mattered when a note's useful lifespan was measured in weeks.
