Watch List notes:

Potosi, Bolivia, cob 8 reales, 1658E, denomination 8 above cross, Royal-like. S-P37a; KM-21; CT-443. 27.80 grams. Excellent full cross-lions-castles and pillars-and-waves (the latter slightly off-center but with nice full crown at top), full king's name and ordinal, three dates (full 1658 in legend) and mintmarks and assayers--in short, clearly in the category of a "pseudo-Royal," and also somewhat rare with denomination above cross (most have a pomegranate), VF with toning around details and minor edge-splits.

Estimate: $600 - 900
