João VI 4000 Reis 1816-(R) MS63 NGC, KM312, Russo-578. Choice Uncirculated withhold apricot toning, full mint luster and only trivial handling marks and a slight weak strike area likely preventing a higher designation. A handsome example of this very elusive one-year type with "REGENS" on the obverse legend, rare and most desirable in this quality and with a now legendary pedigree. Ex.
