Mexico 1751-Mo M 2 reales

from the Mountain Groan Collection

close up of the date

This 1751 two reales is one of a series struck 1747-60 during the reign of Ferdinand VI (1746-59). Gilboy^[1] notes the date as common; two rare overdates are mentioned, 1751/49 and 1751, 5/4.

Mexican numismatists hotly debate which side of the coin constitutes the obverse. Gilboy^[1] 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, .200 troy oz ASW.

Catalog reference: Cayón-10391, Gilboy M-2-24, KM 86.1.
