Watch List notes:

Potosi, Bolivia, cob 8 reales, Philip II, assayer B (1st period), rare. S-P4; KM-5.1; CT-139 (under Lima). 26.46 grams. What distinguishes 1st-period B (which is rare) from later periods is the border of fine, tight dots separating the legends from inner details on each side, which this specimen shows clearly, also with bold ISPANI(ARVM) that appears to lack the H but based on the spacing we believe the H is just flat (compare with Paoletti #67 versus Sellschopp #38), the shield and cross being very choice and well detailed (great for die study), also with full crown and full P-B, all on a broad flan with peripheral flatness, AXF overall with some spotty toning. Pedigreed to the Christensen auction of April 1972, with original lot-tag #2117.

Estimate: $500-750
