Watch List notes:

Potosi, Bolivia, cob 8 reales, Philip II, assayer C under erasure, very rare. 27.35 grams. Perfectly round flan with choice full shield, full crown and cross, much bold legend, also full denomination o-VIII, but rarity and value come from the clear P-erasure-C that seems to be slightly different on each coin and therefore worthy of study by the experts to see just what was erased (probably B/L), an issue that was attributed to La Plata until new research in 1988.

Estimate: $1750 - 2500
