Bolivia 1743-P C 8 reales
The Spanish colony of Upper Peru produced hammered cob coinage at the Potosi mint from 1573 to 1773, with a major debasement scandal and subsequent reform occurring in 1649-1652. The period 1767-1770 saw simultaneous issue of milled columnarios. The royal or presentation issues are very rare and highly sought after, while the regular strikes vary in price according to the visibility of the date, mint, and assayer initials.
The specimen shown was lot 646 at Cayon Subastas auction held February 4, 2012, where it sold for 65 euros (about $101 including buyer’s fees). The catalog description noted "Potosí. 8 reales. 1743. C. BC/MBC. A pesar de tener un peso correcto, este ejemplar parece una fundición del XVIII-XIX, quizá emitida en el Norte de Argentina.. (Potosi 8 reales, 1743-C. Fine to very fine. In spite of having correct weight, this example appears to be a product of the 18th to 19th century, perhaps issued from the north of Argentina.)"
