POLAND. 2 Ducats, 1660-GBA. Lviv Mint. John Casimir. PCGS AU-58. Fr-89; Kop-1910; H-C-5911 (R5). This Polish beauty struck during the reign of John Casimir has an attractive muted look to the surfaces, with more brilliant patches shining through. A slight doubling is visible on the portrait and legends, which is not uncommon for Polish issues from this period. The reverse legend is inscribed with the initials GBA short for Giovanni Battista Amuretti, the leaseholder for the Lviv mint. Very light evidence of wear on the hair of the portrait determines the grade, yet the surfaces remains free from noteworthy marks and nicks. From the Mark and Lottie Salton Collection.
