This specimen was lot 73336 in Stack's Bowers Collectors Choice sale (Costa Mesa, CA, September 2024), where it sold for $900. The catalog description[1] noted, "BOLIVIA. Cob 8 Reales, 1636-P T. Potosi Mint. Philip IV. PCGS VF-20. A satisfying problem-free Bolivian cob featuring both of the final date digits quite clearly. Attractive surface quality with an aged silver look. This piece stands as a solid representative of the date. From the S.P. Rutherford Collection." Royals are known of this type from the Potosi mint for 1630-48 but all are rare. The regular cob issues are not nearly as nice. The 1649-52 was a period of reform at the Potosi mint; it was found that the previous mintmasters in office 1625-48 had been debasing the cobs, a crime for which one official paid with his life. This example may be as low as 0.750 fine.
Recorded mintage: unknown.
Specification: 27.07 grams, 0.931 fine silver (if full fineness), .810 troy oz ASW, this specimen 26.06 g.
