Watch List notes:

Potosi, Bolivia, bust 4 escudos, Charles IV, 1803PJ, very rare, NGC AU 53, finest and only example in NGC census. CT-254; KM-80. Bold strike and beautifully lustrous, also faintly toned, looks MS or at least AU 58 but with a couple tiny marks restricting its grade (also small natural flaws on cheek), still remarkable as the ONLY example slabbed by NGC or PCGS and therefore the finest specimen on record. NGC #4226247-011.

Estimate: $3500-5000
