Germany 1923, Inflation Series, 5,000,000,000-mark stamp in sienna and yellow orange, typographically printed by the Reichsdruckerei in Berlin and issued on November 12, 1923, at the apex of the Weimar Republic’s hyperinflation. The stamp measures 22 x 26 mm and is printed on paper with upright 'waffle' watermark, featuring roulette 13 perforation. Issued as a regular postage stamp in full sheets of 100, this example is in mint never hinged (MNH) condition. Catalogued as Michel DR 327BP, Scott DE 307, Yvert et Tellier DR 328, Stanley Gibbons DR 339, and Unificato DR 328, it also includes three recognized minor varieties. As one of the highest-denomination issues of the hyperinflation era, the stamp exemplifies the severity of Germany’s monetary collapse in late 1923, when postage values reached the billions. The sheet's exceptional preservation enhances its historical, philatelic, and cultural relevance as a testament to the dramatic inflationary spiral. Estimate "$90 – 110"
