Very beautiful German tumbler / antique silver cup, 19th century, 13 DK hallmark. Engraved / Napoleonic III period, from the 1867 Universal Exposition. There is a small dent from use at the base. This hallmark indicates a silver purity of 13 Loth (equivalent to 812/1000 purity), associated with the initials of the silversmith or master assayer “DK”. The Loth (or Löthige) system is an old unit of purity mainly used in Germany and German-speaking regions until the hallmarking system was unified in 1888.
The number 13: in this system, pure silver corresponds to 16 Loth. A piece marked 13 therefore contains 13/16 pure silver, which is exactly 81.25% solid silver (812 thousandths). The letters DK: this is the mark of the silversmith or manufacturer responsible for the piece, or sometimes a control code linked to a specific German city (reference works such as the Beuque dictionary list several “DK” hallmarks in the Germanic sphere without always identifying a single name). Height 8.5 cm, diameter 7.4 cm, weight 84 g; decorative display piece with a small dent from use at the base.
