João VI gold 6400 Reis 1822/0-R AU58 NGC, Rio de Janeiro mint, KM328, cf. LMB-591 (unlisted overdate), Guimaraes-1822/20-1a. Mintage: 599. An outstandingly rare issue from the entire Brazilian series, this highly coveted piece rises above the Pedro II 1822-R 6400 Reis in rarity (16 known). Despite not having the "1st Issue from Independent Brazil" symbolism, the present offering can be regarded with the title of "Last Brazilian Issue under Portugal." Guimaraes notes only 6 examples surviving to present day, with only a single other brought to market, an NGC AU53. While 8 pieces are accounted for by NGC and PCGS combined, we have located 2 of them and verified that they are in fact Portuguese 1822 6400 Reis from the Lisbon mint (no mintmark after date), a reason that leads us to believe a fraction of the certified population can be Portugal and not Brazil. All remaining specimens share the same pair of dies, described by Guimaraes as being a re-worked obverse die from the 1820 issues (which we were able to verify in this piece upon close inspection). The offering presents lightly toned, crisp, and semi-glossy surfaces with an appealing sheen. Missing from the Eliasberg, Norweb, RLM, and even the BES (Banco Espirito Santo) collections, the latter of which is considered the most complete collection of Brazilian gold coins, this immense rarity is the single piece to be auctioned in the last 20 years and is sure to excite advanced Brazilian type and trophy coin collectors. From the Petropolis Collection, Part III
