João Prince Regent "Special Series" gold 4000 Reis 1816(R) AU58 NGC, Rio de Janeiro mint, KM312, Fr-96, LMB-O578. An exceptional near-mint example of this scarce and desirable one year type referring to João by his full title in Latin as 'prince regent' (princeps regens). With a great deal of underlying luster, only a hint of light wear prevents a higher grade.
