Hardenberg-Neviges was a small industrial town in the Bergisches Land region of western Germany, and like hundreds of German municipalities in 1923, it was forced to print its own emergency currency as Reichsbank notes lost purchasing power faster than they could be distributed. These municipal million-mark issues — Notgeld in the inflation's most extreme phase — were often valid for only days before redenomination rendered them obsolete. A note issued in July could be worthless before August ended.

The sheer volume of Notgeld printed by minor authorities that summer means many types survived in quantity, but specific Hardenberg-Neviges issues remain thinly documented in major catalogs.
