Mexico 1770-Mo MF 8 reales
This is one of a series struck 1760-71 during the reign of Charles III (1759-88). Many varieties exist for the year, including overdates and changing of the assayer initials from MF to FM. The example shown is common.
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.
