Watch List notes:

Potosi, Bolivia, cob 8 reales, 1733YA, rare. S-P45; KM-31a ;CT-891. 25.95 grams. Well-centered specimen with full inner details, bold assayer and parts of the other two, both dates and all three mintmarks clear, VF with toning, really one of the best specimens of this rare and desirable short-lived assayer, of whose work this date is arguably the rarer (not to mention that the 1732 is plagued by convincing fakes).

Estimate: $1000 - 1500
