A 100 million mark Reichsbank note dated Berlin, 22 August 1923, printed on one side only. The front shows the value 'Einhundert Millionen Mark' in bold Gothic lettering on a patterned green panel, with directors' signatures and two eagle seals, and a large 100 to the right. The text allows the note to be called in from 1 October 1923. It dates from the most rapid phase of the German hyperinflation.
What it boughtFrom 24 August 1923 an inland letter cost 20,000 marks to post, so this note paid for 5,000 letters.
