João VI gold 6400 Reis 1820/19-R MS61 NGC, Rio de Janeiro mint, KM328, cf. LMB-589 (unlisted overdate), Guimaraes-1820/19-3a. Mintage: 3,286. The second-most collectible key-date of the series, not considering the unique 1821 piece (part of the National Museum's Collection in Rio de Janeiro), this scarce and coveted issue is presented with a remarkable level of preservation. Retaining razor-sharp motifs and luminous fields, it is dressed in a lovely flame-gold patina that does little to obscure the shades of original luster. Despite NGC distinguishing 1820 and 1820/19 examples, Guimaraes notes that all 1820 issues are 1820/19, a fact that we have observed in all pieces sold in recent decades. Much finer than RLM's AU Details (Repaired) piece, this appealing example will likely garner the attention of advanced Brazilian type collectors. Ex. Numisma Auction 76 (November 2008, Lot 104) From the Petropolis Collection, Part III
