Germany 50 pfenning 1921 Notgeld - City of Lorch am Rhein - 100 years old

Notgeld  (German for 'emergency money' or 'necessity money') is money issued by an institution in a time of economic or political crisis. The issuing institution is usually one without official sanction from the central government. This usually occurs when not enough state-produced money is available from the central bank. In particular, notgeld  generally refers to money produced in Germany and Austria during World War I and the Interwar period. Issuing institutions could be a town's savings banks, municipalities and private or state-owned firms. Nearly all issues contained an expiry date, after which time they were invalid. Issues without dates ordinarily had an expiry announced in a newspaper or at the place of issuance.
