Watch List notes:

Potosi, Bolivia, cob 8 reales, 1647P, extremely rare. 28.72 grams. With clear tops of the 647 of the date and full and clear •P assayer, this coin is only the second example we have seen or heard of, its extreme rarity no doubt due to the recall and melting of 1649-52 (although it is interesting to note that this example is quite a bit OVERweight), with nice full shield and cross but the peripheries (except the date, by sheer chance) somewhat crude and flat and split, lightly toned all over, Fine+. Pedigreed to the Cayon auction of February 2012 (lot #324, mis-described as 1621-31).

Estimate: $700 - 1000
