MEX 1770 M-2-45 A1-A1 HA-lot62196-14May2015-USD342-rev.jpg

This 1770 two reales is one of a series struck 1760-71 during the reign of Charles III (1759-88). Gilboy[1] notes the date as very rare (R3). There is no major variety noted for this year, though there is speculation that a type exists with assayer initial 'F'.

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, 0.200 troy oz ASW.

Catalog reference: Gilboy M-2-45, KM 87.
