"1752. Fernando VI. Potosí. q. 8 reales. Marcas de ceca y ensayador en posiciones intercambiadas. Esta fecha no figuraba en la Colección Sellschopp, con éste peculiar reverso, no consta en Krause. Rarísima con el ordinal del rey erróneo. ¿Única conocida?. MBC+/MBC. (kingdom of Spain, Ferdinand VI, eight reales of 1752, Potosí mint. Mintmark and assayer's initial interchanged; not shown in the Sellschopp collection or in Krause. Extremely rare error, the only one known? Very fine.)"
The Spanish colony of Upper Peru produced hammered cob coinage at the Potosí 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.
Recorded mintage: unknown.
