MEXICO. Peso, 1912. Mexico City Mint. PCGS MS-65. KM-453. A staggering exemplar, this stunning Gem "caballito" Peso offers exceptional brilliance and toning, and has remained fairly untoned for the past century-plus. A few burnished spots are noted at portions of the peripheries, but that is the extent of the non-argent characteristics. A tremendous opportunity, and at a grade level that is exceeded in the PCGS census by just four examples.
