From the German roots “not” (necessity) and “geld” (money). Notgeld were produced by almost 3500 German and Austria towns and cities from 1914 to 1922. Colorful little notes printed surface (rather than engraved). Most notgeld were issued in small denominations of 1 mark or less 50 Pfennig, 25 pfennig, etc.
