Mexico 1760 8 reales rev 600.jpg
Aureo sale 232, lot 194

This is one of a series struck 1760-71 during the reign of Charles III (1759-88). Gilboy[1] notes numerous varieties for the date, most important of which is the king's name. This specimen bears the name of CAROLVS III; others bear the name FERDIND VI. Both types are common for 1760. King Charles' half-brother Ferdinand died early in 1759 but with slow communications the news did not arrive in Mexico until the next year.

The second specimen shown was lot 194 in Aureo y Calicó sale 232 (Barcelona, March 2011), where it sold for 240 euros (about $396 including buyer's fees). The catalog description[2] noted,
"1760. México. MM. 8 reales. Columnario. FERDND bajo CAROLVS. Bella. Precioso color. Escasa así. EBC. (Eight reales of 1760, Mexico City mint, pillar type with CAROLVS over FERDND. Nice, handsome color, scarce thus, extremely fine.)
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: 27.07 grams, .917 fine silver, .798 troy oz ASW.
