1944 Germany 1 Mark WWII Allied Military Currency P# 192a, 9 digit with F Grades Choice AU/BU Slider. The AM-Mark ("Allied Military Currency") was the currency issued in Allied-occupied Germany by AMGOT after the commencement of Operation Wild Dog in 1944. There were individual prefix identifications for Occupation zones (USA > 1, British > 0, French > 00, Russian > -). These notes circulated through mid 1948. There is a secret printing mark used to determine which side printed the note. For the Americans this is a stylized "F" for the printer, Forbes Lithographic, which appears on the 1/2, 1, 5 and 10 mark notes in the left ball of the scroll directly below the lower right denomination value. The letter also appears on the 20, 50, 100 and 1000 marks. The Soviet Union printed identical notes but without the "F".
