This type was struck between 1789 and 1805 in Rio and features the bust of Maria, queen of Portugal 1786-1816. While the 6400 réis is relatively available, its fractions (3200 réis, 1600 réis and 800 réis) are much scarcer. This type was also struck in Bahia (KM 226.2) during this period. This coin was called the "joe" in English speaking countries. This specimen was lot 23265 in Heritage sale 3012 (New York, January 2011), where it sold for $1,667.50. The catalog description[1] noted, "Maria I gold 6400 Reis 1799R, MS61 NGC, full original mint bloom, a flashy coin and far more attractive than the NGC designation might suggest."
