50 Pfennig

Hamm's 1920 Notgeld issue belongs to the first wave of municipal emergency currency printed across Germany as the Reichsbank struggled to keep small-denomination coin in circulation following the war. Cities and towns were effectively left to supply their own fractional currency, and the results varied wildly in quality — Hamm's series falls on the competent but unspectacular end of that spectrum. The printing was handled locally, which was common for Westphalian municipalities of this size.

Short-term validity clauses on notes like these meant most were redeemed and destroyed within months, making intact survivors more common in collector holdings than in worn circulated grades.
