Bolivia 1705-P Y 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 the 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. This specimen was lot 1701 in Sedwick sale 25 (Winter Park, FL, May 2018), where it sold for $142.80. The catalog description noted, "Potosi, Bolivia, cob 8 reales, 1705Y. Heavily scratched and crude, but with two dates and nearly full king's name, full pillars-and-waves, toned VG."
