Watch List notes:

Potosi, Bolivia, cob 4 reales, Philip II, assayer C under erasure, very rare. S-P5; KM-4.2; CT-307 (under La Plata). 13.72 grams. Broad, round flan with choice full inner details and nearly full legends, XF with contrasting toning (some dark spots), particularly bold P-erasure-C. It is interesting to note that Sellschopp did not mention this denomination of this issue (which he considered to be La Plata in error) in his main book (Las Acunaciones de las Cecas de Lima, La Plata y Potosi [1971]), but he did list it without photo in his collaboration with Grunthal (The Coinage of Peru [1977], coin #295A), in reference to a specimen presented by Kurt Dym in the December 1971 issue of Gaceta Numismatica. We have seen others in the meantime, but the present specimen, in its first appearance in any publication, is the best example we have offered.
