Peru 1770-L JM 4 reales
This specimen is of the series struck 1760-1772 during the reign of Charles III (1759-88). No varieties are reported for this date, which is considered very rare by Gilboy. As a class, pillar coinage of Peru is much less plentiful than that of Mexico, tho it is more available than the remaining mints. Harris encountered about one-third as many Peru pillar four reales of Charles III as that of Mexico.
Mexican numismatists hotly debate which side of the coin constitutes the obverse. Gilboy depicts the shield side as the obverse as that side bears the king's name. However, auction catalogs and dealer listings more frequently use the pillars and globes side as the obverse, as that side bears the date.
Recorded mintage: unknown.
