Watch List notes:

Potosí, Bolivia, cob 8 reales, Philip II, assayer B (late 3rd period). S-P10; KM-5.1; CT-158. 27.22 grams. Perfectly round and somewhat concave flan with choice full shield and cross (all slightly doubled), much legend and crown, AVF with natural interior flan-crack. Note the box-like borders of this style make some believe it is variety of 5th-period B, but commas in the legend and other details point to late 3rd period to us.
