Watch List notes:

Potosi, Bolivia, cob 8 reales, Philip II, assayer C-under-erasure, very rare. S-P5; KM-5.1; CT-136 (under La Plata). 27.70 grams. This is the finest specimen we have ever offered of this popular issue (once believed to be La Plata), with very clear letter B (actually B/L) inside the erasure between the clear mintmark P and bold assayer C, also with well-detailed full shield and cross and crown and much legend (full PHILIPPVS), just a trifle doubling and flatness but with nice toning around the details, XF.
