Bolivia (1598-03)-P B 1/2 real
This specimen was lot 73414 in Stack's Bowers Collectors Choice sale (Costa Mesa, CA, October 2025), where it sold for $125. The catalog description[1] noted, "BOLIVIA. Cob 1/2 Real, ND (1596-1603)-P B. Potosi Mint. Philip III. PCGS FINE-15. From the Richard August Collection." 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 Potosí mint was the second mint in the western hemisphere to date its products. Dating began in 1617.
Recorded mintage: unknown.
Specification: 1.71 g, 0.931 fine silver, this specimen 1.81 g.
