    An Extreme Rarity from Brazil

    Joao V gold 12800 Reis Dobra 1731-R "Italic Shield", KM148, AU53 NGC, sharp details with bright orange patina. Light circulation on the high points, reverse is near mint state with complete tower details and full mini-shields. The 1731 Dobra from the Rio mint with the so-called "Italic Shield" is extremely rare with only a handful of pieces known to exist, most of which are in private museums. As a short-lived type, the 12800 Reis were struck at the Rio de Janeiro mint from 1727 to 1733. Very late in 1731, the Dobra's reverse was redesigned to feature a new polygonal shield to substitute the circular (oval) one which had been used only on "R" mint coins up to that year.

    Gomes (#138.10) simply lists this coins as "rare". This type has been absent from all major Brazilian/Portuguese sales of the last two decades including Norweb. This piece is in nicer condition than the one in the "Espirito Santo Collection"--the most important collection ever assembled of Portuguese and Portuguese colonial coins and the only other piece found in our research.
