The Memorial tankard of Dorothy de Talleyrand-Perigord and the numismatic collection of the birons of Żagań

Inscribed with an engraved name of Dorothy, princess of Courland and duchess of Żagań (1793–1862), a tankard from 1845 is stored at the National Museum in Warsaw. A total of 46 coins and medals selected specifically to present the history of House of Birons, that Dorothy descended from, adorn its sides. Only scanty reports remained about the family’s numismatic collection, gathered in the 18th and 19th century and partially included in such adorned vessels.
