Mexico 1758-Mo M 2 reales
This 1758 2 reales is one of a series struck 1757-60 during the reign of Ferdinand VI (1746-59). It shows dissimilar crowns atop the pillars on the date side. The regular issue for this year is listed as uncommon by Gilboy. The example shown, however, is an unlisted variety with cross stops on the reverse instead of five-petalled rosettes.
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.
Specification: 6.77 grams, 0.917 fine silver, 0.200 troy oz ASW.
