Joao V gold 6400 Reis 1748-R AU58 NGC, Rio de Janeiro mint, KM149, Russo-223. Most attractive in this quality, with luminous, golden-amber color and a minuscule amount of friction noted atop the devices. With very few marks in the fields, and featuring a nicer than usual portrait of Joao V, this selection boasts originality and appeal all in one.
