Bolivia (1586-89)-P A 8 reales
This specimen was lot 538 in Sedwick Treasure Auction 27 (Winter Park, FL, May 2020), where it sold for $1,413.72. The catalog description noted, "Potosi, Bolivia, cob 8 reales, Philip II, assayer A. Exceptionally well-detailed full shield and cross (very slightly doubled), nearly full legend and crown, full P-A and denomination o-VIII, full cross-fleury ornament above cross, XF with lovely toning around details." The mountains around Potosi contained enormous amounts of high grade silver ore, a situation the Spanish were not slow to exploit. A mint was set up in the 1570's to process the silver mined there. The early products of the reign of Philip II are fairly good quality but rot set in during the following reign, including fraudulent debasement. The Potosi mint was the first mint in the western hemisphere to date its products. Dating began in 1617.
Recorded mintage: unknown.
