This is one of a series struck 1767-70 during the reign of Charles III (1759-88). Gilboy[1] lists the date as "rare" with several varieties recorded.

The pillar four reales is somewhat rare although all dates are available. In 1771, milled coinage was suspended at the Potosi mint in favor of the resumption of cob production. The mintmaster was rebuked for this and forced to return to milling coins in 1773 with the introduction of portrait coinage.

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: 13.54 g, 0.917 fine silver, 0.39 troy oz ASW.
