Mexico 1771-Mo F real
The specimen shown was lot 1280 in Sedwick sale 11 (Winter Park, FL, April 2011), where it sold for $299. The catalog description noted, "Mexico City, Mexico, pillar 1 real, Charles III, 1771F. Broad-flan XF with full rims, deep and even toning, minor die-cracks on shield side, scarce final year (R3 in Gilboy)." 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.
Recorded mintage: unknown.
Specification: 3.38 grams, .917 fine silver, .099 troy oz ASW, the first specimen 3.3 grams.
Catalog reference: Cayón-11311, KM-77; CT-1552, Gilboy M-1-47.
