    João V gold 6400 Reis 1727-M VF Details (Surface Hairlines) NGC, Minas Gerais mint, KM135, LMB-278, Bentes-112.01 (R3). An unbelievable rarity of the Brazilian numismatic series, the first year of issue for this denomination, and perhaps the very first time an example from this mint has been offered at auction. Despite production of the 6400 Reis beginning in 1727 and continuing until 1734, examples are seldom seen from any other years than 1733 and 1734, and even these are extremely rare. We have had the privilege to previously offer two examples of the 1727 6400 Reis, one struck at the Bahia mint and the other at Rio de Janeiro at our January 2012 auction (both graded AU Details, realizing $110,000 and $125,000 hammer respectively), but this is the first time we have offered such a specimen from Minas Gerais. Bright and sunny in color, moderately circulated in line with the grade yet retaining strong detail; somewhat altered surfaces (likely from time spent in jewelry), but to no great visual detriment. From its extreme rarity, it will come as no surprise that this is the sole certified example by NGC or PCGS. For the advanced Brazilian collector, this may be your only chance to obtain a Minas Gerais-struck 6400 Reis from the first year of its production.
