Watch List notes:

Potosi, Bolivia, cob 8 reales, 1676E, Calbeto Plate Coin. 25.84 grams. Very crude coin with low contrast due to dark toning, but with two dates and mintmarks, three assayers, one nice crown, Fine with surface roughness (as made?), but most desirable for its pedigree (this date considered rather scarce in Calbeto's time but now more common due to the Consolacion wreck of 1681). Plate Coin #1081 in Calbeto's Compendium VIII Reales (1970).

Estimate: $200 - 300
