Potosi, Bolivia, bust 1/2 real, Charles IV, 1805 PJ, NGC MS 65+. Janson-80.17.2; Cal-315; KM-69. Deeply rainbow toned over full luster, the obverse with strong purple ring around a deep magenta center, no marks or wear, second finest in the NGC census behind a single MS 67-star (the only 67 in the whole colonial series) that in our opinion is imperceptibly nicer than the present piece.
