Mexico 1765-Mo M 1/2 real

from the Mountain Groan Collection

The 1765MoM is one of a series of half reals struck 1760-1771, during the reign of Charles III. Gilboy^[1] lists this date as common. He records no varieties for the date.

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.
