This striking German Official (Dienstmarke) stamp dates from the peak of the 1923 hyperinflation crisis, when face values were reprinted almost weekly. The original 15 Pfennig red-brown Official design has been boldly overprinted with “400 Tausend” (400,000) in black, reflecting the astronomical currency collapse of late 1923. The ornate numeral background contrasts with the heavy emergency surcharge, a typical hallmark of the period. Such surcharged Official stamps are prized for documenting Germany’s economic turmoil and postal improvisation. A compelling historical piece for any inflation-era or German States collection.
