Watch List notes:

Potosi, Bolivia, cob 8 reales, 1748 q, NGC AU 50. S-P50a; KM-40; Cal-510. 26.68 grams. Choice full pillars-and-waves and cross-lions-castles, both well centered and fully detailed, two dates, three mintmarks and assayers, with contrasting dark sediment in crevices, very slight surface porosity on high points that seems to be the only thing keeping this from tying or bettering the previous lot, to which this one is second finest in the NGC census.
