Watch List notes:

Potosi, Bolivia, cob 2 reales Royal, 1686VR, very rare. S-P40; CT-unl; KM-R24. 5.94 grams. Broad and round as it should be, but a bit worn (Fine) and uneven, also slightly bent and with tiny hole at top (axes aligned), with light toning. We can confirm only one other example, in Christensen's Faistauer auction of 1979, as we suspect that is the same coin in the "Americas" collection sold by Kagin's in 1983 (no photo in catalog). It is odd that CT does not list it despite those two appearances. ($600-900)
