Brazil 1828-B 6400 reis
This specimen was lot 23091 in Heritage sale 3030 (New York, January 2014), where it sold for $8,225. The catalog description noted, "An Exceptional Survivor of a Rare Issue. Pedro I gold 6400 Reis 1828-B, AU53 NGC. Attractive for the grade with gleaming surfaces that highlight few marks and legends that are adorned with whispers of peach-colored tone. The strike, on this and essentially all Bahia mint 6400s of this date, is short of perfect, and while the peripheral legends rise to full completeness, some design bluntness is apparent in the obverse and reverse centers. When all is considered, this is certainly among the finest survivors of the date, and it is particularly notable as a problem-free example. Expect fierce competition." This gold 6400 réis or peça was minted at the Rio and Bahia mints 1823-30. All the dates are rare. It is nearly the last of a denomination introduced in Brazil in 1727.
Recorded mintage: 423.
Specification: 14.34 g, .917 fine gold, .422 troy oz AGW.
Catalog reference: KM 370.2, Russo-608, Fr-109.
