POLAND. Lithuania. Ducat, 1666-TLB HKPL. Vilnius Mint. John Casimir. PCGS AU-55. Fr-9; H-Cz-5928 (R7); Kop-3631 (R7); Kur-822 (R8); Gum-1874. Weight: 3.30 gms. Obverse: Laureate bust of John Casimir right; further encircled by laurels; Reverse: Arms of Lithuania, the Vytis; above: crown; encircled by laurels. One of the most exciting offerings of this entire collection, this Ducat of John Casimir features a distinctively Lithuanian flair. This piece is somewhat less refined than one is accustomed to seeing on Polish gold from this era, with some roughness to the flan and a crudity to the engraving. All of this only adds to the charm that is already present in this example resultant from its <strong>RARITY</strong>. Almost no actual circulation is seen, and good luster is yet present on the flan. For completeness, we note that there appears to be metal movement on the edges, perhaps indicating past usage in jewelry. From the Anthony J. Taraszka Collection. <p>Ex: Ahlstrom 62 (11/2000) Lot #1539.
