Bolivia 1665-P E 8 reales
This specimen was lot 583 in Sedwick Treasure Auction 27 (Winter Park, FL, May 2020), where it sold for $476. The catalog description noted, "Potosi, Bolivia, cob 8 reales, 1665E, date below cross as 665. Bold full pillars-and-waves (the tops particularly sharp), good full cross, three dates, bold king's name and ordinal, VF with light surface porosity." Royals are known of this type from the Potosi mint but all are rare. The regular cob issues are not nearly as nice. The years 1649-52 were 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.
Recorded mintage: unknown.
