Courland. Peter Biron gold Ducat 1780 MS63 NGC, KM33, Fr-4. A highly attractive one-year type, featuring brilliantly lustrous fields and a pleasing light golden-orange tone near the peripheries. The most attractive which we have had the pleasure of offering, and likely the finest known. A few light adjustment marks near the edge on the obverse are noted for completeness only, as they do not detract from this piece's charm and appeal.
Estimate: 5000-6000 USD
