Mexico 1752-Mo M real
This 1752 is one of a series struck 1747-1760 for Ferdinand VI. It is distinguished from later issues (KM 76.2, 1757-60) of pillar one reals by having similar crowns atop the pillars on the date side. The variety shown is unlisted, as there is no reported 'unbarred H' in the abbreviation HISP for this date. As such the rarity is unknown.
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.
