Ponterio sale 150, lot 9184

This coin was lot 9184 in Ponterio sale 150 (Los Angeles, August 2009), where it sold for $1,207.50. The catalog description[1] noted, "MEXICO. 1/2 Grano, 1769. RARE, minor encrustation. VERY FINE." This was another failed experiment to circulate base metal coinage in the Spanish American colonies, which situation must have annoyed the authorities no end when they saw large quantities of copper coins circulate in Brazil.

Recorded mintage: Unknown.

Specification: copper.

Catalog reference: KM-PnC1 (not listed in most editions of the SCWC; see the edition cited below).
