Guatemala 1759-G P 8 reales
This specimen was lot 20463 in Ponterio sale 161 (Chicago, August 2011), where it sold for $17,250. The catalog description noted, "GUATEMALA. 8 Reales, 1759-P. The only NGC certified mint state example of a Ferdinand VI pillar dollar. Well struck, fully lustrous with a hint of light adjustment marks on the obverse, population 1 of 1 for this king. NGC MS-64."
Unlike the other colonial mints, Guatemala seems to have issued more four reales than any other denomination. Gilboy marks the half, one and two reales as "rare" and the eight reales as "scarce" to "normal." None are marked as common. Guatemalan issues are notably cruder than other mints. Mexican numismatists hotly debate which side of the coin constitutes the obverse. Gilboy 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.
