This is one of a series struck 1767-70 during the reign of Charles III (1759-88). Gilboy[1] lists the date as "normal" (more than 500 pieces known to exist) with numerous varieties recorded. The specimen shown is a "fancy 9/8," and is a slightly scarcer variety. The four reales is the scarcest colonial denomination although all dates are available except for the rare 1767 date. Harris[2] lists the Charles III pillar four reales in order of abundance: Mexico, Potosi, Guatemala, Lima (scarce), Santiago (very rare). Specimens in high grade are very rare. 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 (Gilboy[1] estimates about 72,000).

Specification: 13.54 g, .917 fine silver, .399 troy oz ASW.

Catalog reference: Gilboy P-4-3c, KM 49.
