10 Mark

Uerdingen, a small industrial town on the lower Rhine, was among the hundreds of German municipalities that issued their own emergency paper money — Notgeld — during 1918 as coin shortages bit hard and the imperial monetary system buckled under wartime strain. The city's note-issuing authority here is the municipality itself, not a bank or savings institution, which was common for smaller localities that lacked a formal banking partner willing to take on the administrative burden.

Ten marks was on the higher end for municipal Notgeld of this period; most issues clustered around 50 Pfennig to 5 Mark. Whether this denomination actually circulated heavily or was absorbed into the collector trade almost immediately after issue is an open question — by late 1918, speculative hoarding of Notgeld by collectors had already distorted circulation patterns nationwide.
