Watch List notes:

Potosi, Bolivia, cob 2 reales, 1647Z/R, unique and important, ex-Ponterio "La Capitana" sale. S-P34; KM-14a. 4.26 grams. Bold bottom half of date, full P-Z with clear Z/R, the under-assayer being for Felipe Ramirez de Arellano, who was famous for being convicted and executed for his role in the debasement scandal, of which this coin is a shining example with its very low weight (uncorroded) and dull color (indicating low fineness), an amazing survivor that was supposed to have been melted, with good full shield (partially weak) and cross, nicely toned. Pedigreed to the Ponterio "La Capitana" auction of April 1999, with original lot-tag #3 and original catalog, and with certificate from the salvagers.
