Bolivia (1613-17)-P Q 8 reales
This specimen was lot 22385 in Stack's Bowers ANA sale (Las Vegas, August 2020), where it sold for $312. The catalog description noted, "BOLIVIA. Cob 8 Reales, ND (1613-1617)-P Q. Potosi Mint. Philip III. PCGS VF-35 Gold Shield. Assayer letter (and thus date) incorrectly stated on slab. A well detailed and pleasingly toned cob with visible denomination, mintmark, and assayer. From the BKingdom 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 Potosi mint was the first mint in the western hemisphere to date its products. Dating began in 1617.
Recorded mintage: unknown.
