Watch List notes:

Potosi, Bolivia, cob 8 reales, 1742 C/P, rare, NGC AU 58, finest known in NGC census. S-P49; KM-31a; Cal-1582. 27.30 grams. Choice full pillars-and-waves with bold date and mintmark and both assayers, the cross side somewhat compromised by the chunkiness of the flan (oddly shaped, too, requiring an interesting modification to its slab-frame) but still with clear date and full C/P assayer (not noted on label), light sediment on fields, choice grade.
