10 Pfennig - Flensburg

Flensburg issued its own emergency coinage in 1917 as the Imperial war economy stripped zinc, copper, and nickel from civilian circulation to feed munitions production. These Notgeld pieces were a municipal stopgap — authorized locally to keep small transactions functioning when Reichsmünze-struck coins had effectively vanished from everyday commerce. Flensburg's position as a border city with a mixed Danish-German population gave its wartime issues a particular administrative edge; the question of which authority actually governed daily life there would not be resolved until the 1920 Schleswig plebiscite split the duchy.
