71/2 Pfennig - Ingolstadt G.G.F.

Ingolstadt's wartime notgeld fractional issues were struck to address the near-total disappearance of small change during the First World War, when hoarding and metal requisitions drained conventional coinage from circulation almost entirely. The denomination itself — seven and a half Pfennig — is a product of pure practicality: three pieces equaled a Groschen-equivalent transaction value without requiring the city to issue a 10-Pfennig piece that might compete with imperial currency.

The "G.G.F." suffix identifies the issuing authority as the Geschäftsstelle der Gefangenenlager-Fürsorge, a prisoner-of-war camp welfare organization operating within the Ingolstadt garrison complex.
