Mexico 1756 medio real rev DSLR.jpg

This date is one of a series struck 1747-1759 for Ferdinand VI. In the year following this issue, the crown left of the globes was changed from the royal to imperial type. The first specimen is an overdate, a prominent 6/5. Gilboy[1] lists this particular variety as rare.

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: 1.69 grams, 0.917 fine silver, 0.049 troy oz ASW.

Catalog reference: Cayón-10214 (1756/5), Cayón-10215 (regular date), Gilboy M-05-30a, KM 66.
