Potosi, Bolivia, bust 8 reales, Ferdinand VII, 1813 PJ, error with king's ordinal as IIV, rare, NGC XF 45. Janson-86.3.2; Cal-1376; KM-84. Traces of luster and gray toning over only lightly worn surfaces (the bust just weakly struck), the egregious error a rare and desirable key for the series. Unfortunately, NGC did not attribute the error to this coin, so it does not appear properly in the census, which shows only a single entry for the error (AU 55).
Estimate: 300 - 450 USD
