Watch List notes:

Complete denomination set of Potosi, Bolivia, cob 1/2-1-2-4-8 reales, 1738M. 50.83 grams total. The brave collector who decides to collect all Potosi pillars-and-waves cobs, in all denominations, soon discovers just how long it takes (and how much record-keeping is involved) to acquire all 600+ coins, which is why complete date sets are so useful, this one showing a clear date on each coin (as well as a clear assayer on all but the 1/2R, which did not have one), also with full or nearly full crosses and more or less toned, AVF on average, the 4R particularly nice (and the hardest denomination).

Estimate: $400-600
