Stanislaus Augustus gold Ducat 1791-EB AU58 NGC, Warsaw mint, Ephraim Brenn as mintmaster, KM196, Fr-104. Beautifully toned and lightly circulated, this specimen is the finest certified of this date by NGC and exhibits remarkable detail highlighted by ample residual luster. Uncommonly for Ducats of this period, the surface marks from its short time in circulation are not especially distracting and there is little waviness evident in the flan.
Estimate: 4000-4500 USD
