Watch List notes:

Potosi, Bolivia, cob 4 reales, Philip III, assayer B (5th period), rare. S-P14a; KM-9; CT-241. 13.65 grams. King's ordinal III clear in legend (actually looks like IIII due to doubling), which sets it apart from the common examples with same details but without ordinal that are attributed to Philip II by default, also full shield and cross with slight doubling, VF with dark sediment on fields.
