João V gold 20000 Reis (Dobrão) 1724-M AU Details (Cleaned) NGC, Minas Gerais mint, KM117, LMB-248, Guimaraes-1724-1a. First type, narrow crown. Struck in the province of Vila Rica, where the Portuguese extracted most of the Brazilian gold, this short-lived issue departed from the duodecimal system that included 12,800 Réis coin as its largest denomination. Believed to be one of, if not the largest gold coins ever struck for circulation purposes, it's undoubtedly an imposing piece. Not only the key-date of the series, but the scarcest variety of the date, presenting well-defined and sharp motifs with antique-gold surfaces that would indicate having been cleaned long ago. From the Petropolis Collection, Part I
