Mexico 1777-Mo FM 1/2 real
Shown is an 1777MoFM half real, one of a type struck at Mexico City 1772-84. The bust of Charles III was used until 1789 but later issues were of slightly lower fineness and are catalogued as a separate sub-type. Assayer FM is recorded for the years 1770-77. The half real, as one-sixteenth of a dollar, would have traded in the United States for 6½¢. Harris notes that the Mexico City half real is the only mint that can be called abundant for Charles III, the second mint, Potosi, is less than half as common.
Recorded mintage: unknown.
Specification: 1.69 g, .903 fine silver, .049 troy oz ASW.
Catalog reference: KM 69.2.
