10 Mark

Quedlinburg's 1918 10 Mark Notgeld was issued by the city magistrate under the emergency currency provisions that proliferated across German municipalities as the imperial financial system buckled in the final year of the war. Hundreds of towns issued their own notes during this period, but relatively few bothered with any security feature at all — the perfin on this example is an unusual precaution for a small-city issue, suggesting the magistrate was at least nominally concerned with unauthorized duplication.

Quedlinburg itself was a minor administrative center in Saxony-Anhalt, far from any major wartime industrial or political significance. The note's survival often depends on whether it was redeemed during the chaotic currency stabilization of the early 1920s.
