BOLIVIA. 8 Reales, 1815-PTS PJ. Potosi Mint. Ferdinand VII. NGC AU-55. KM-84; Cal-type 159 #604. An exceptionally pleasing coin with aged brownish tone in the fields and noteworthy amounts of multicolored iridescence on both sides that elevates the eye-appeal. A touch of central softness is noted for the sake of accuracy, but that characteristic is the norm rather than the exception for the date. NGC AU-55.
