Watch List notes:

Potosi, Bolivia, cob 8 reales, 1760Y-q-V, unique (unlisted). 26.67 grams In his seminal 1985 monograph for Cuadernos de Numismatica y Ciencias Politicas (Buenos Aires), Carlos Janson detailed the 1760 transition of assayers from q and q-Y under Ferdinand VI to Y-V and V-Y under Charles III at the Potosi mint; but apparently there was a deeper level to this transition that we are seeing for the first time with this coin, which shows a fairly clear Y at top right, q at bottom left, and V to right of cross (king's name or ordinal not visible). The cross and pillars-and-waves are full, with parts of all three dates visible, typically chunky Fine with edge-crack, toned around details.

Estimate: $500
