Mexico 1740-Mo MF 4 reales
This is one of a series struck 1732-47 during the reign of Philip V (1700-46). The regular issue for the date is considered by Gilboy to be scarce. The first example shown is a 1740/30 overdate, which lists as very rare. The four reales is the scarcest colonial denomination although all dates are available except for the very rare 1732 and 1733 dates. Harris lists the Ferdinand VI pillar four reales in order of abundance: Mexico, Guatemala, Lima (scarce). Specimens in high grade are very rare.
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.
