Watch List notes:

Potosi, Bolivia, cob 8 reales, 1770V-J, very rare. 22.96 grams. Thick and chunky flan, as usual (but inexplicably low in weight), with bold cross and pillars, clear date and full assayer V at top right, the assayer at bottom right decidedly not Y and therefore assumed to be J, AVF for era with toning and verdigris around details.

Estimate: $500 - 750
