Silesia-Liegnitz-Brieg. Johann Christian & Georg Rudolf gold Ducat 1610 MS64 NGC, Reichenstein mint, KM102, Fr-3166. Christoph Tuchmann as mint official. A highly lustrous piece with flashy fields nearly devoid of marks and well-struck portraits of the dukes. There is a faint wave to the flan, but it is not especially distracting.
Estimate: 6000-7000 USD
