Rio de la Plata 8 Soles 1815 PTS-FL AU58 NGC, Potosi mint, KM15. Variety with S/R in the denomination. Lustrous Borderline Mint State with slight high-point wear defining the grade and attractive golden toning. A very popular and historical type - this design and the similar 1813 PTS-J 8 Reales represent the first independent crown of South America. Quite elusive and most desirable in this quality.
Estimate: 800-1000 USD
