BOLIVIA. Silver 4 Soles Pattern, 1827-PTS JM. Potosi Mint. NGC PROOF-63. KM-Pn1; Guttag-304C. An <strong>EXTREMELY</strong> <strong>RARE</strong> pattern only issue, quite possibly <strong>UNIQUE</strong>. This highly interesting type is completely different than those struck for circulation. Depicting a much thinner plain bust of Bolivar without laurel wreath on the obverse, while the reverse is identical to that of the circulation issues. The strike is sharp with hard flashy surfaces and crisp well-defined devices displaying a thin layer of mottled patina. A real treat for the advanced Bolivian collector seeking hard to locate special issues. From the Pat Johnson Collection.<p>Ex: Norweb Collection (Christies Dallas 11/1985) Lot # 607.<p>Possibly Ex: Guttag Collection.
