BOLIVIA. 8 Soles, 1845-PTS R. Potosi Mint. NGC MS-61. KM-103. A softly lustrous gunmetal ray specimen with magenta-gray undertones and hints of iridescent blue. A rather bold strike presents more detail than is to usually be expected from the grade. With only 3 others listed finer in the NGC census, the numismatist who wins can feel confident they posses a premium offering.
