Maria I gold 6400 Reis 1792-R AU58 NGC, Rio de Janeiro mint, KM226.1, LMB-O530. If not for some light handling on the obverse which crosses through the bust into the rightmost field, this piece would almost certainly grade Mint State, as there is seemingly no wear on the devices. Highly lustrous and beautiful in this condition.
