Watch List notes:

Potosi, Bolivia, cob 8 reales, Philip II, assayer B (3rd period). S-P10; KM-5.1; CT-158. 26.91 grams. Broad flan (in fact same diameter as what Sellschopp considered "Great Module" in earlier types) with bold legends and choice full crown and inner details, interesting apparent mix of castles on reverse (bottom-right castle very crude like Sellschopp #177 but top-left castle with four windows like Sellschopp #182), rather close to AU for grade.

Estimate: $350-500
