Watch List notes:

Potosi, Bolivia, cob 4 reales Heart, 1720 Y, unique, NGC plated / holed, ex-Pat Johnson. Janson-unl (Type C34); S-P43a; KM-unl; Cal-unl (Type 144). 13.86 grams. This fabulous coin was obtained by Pat in the 1990s so quietly that the date 1720 never made it into current standard references (Janson, and Calico) nor any older references (like Pellicer i Bru), and was unknown to us when we presented our article about Hearts in Sedwick Auction 18 in 2015 (please refer to that article for more information about these special coins) or our presentation at the 1st International Convention of Historians and Numismatists in Potosi in 2016. We have to assume it is still unique. It is also incredibly well preserved, lustrous AU in our estimation, with lightly gilt surfaces that prevent NGC from rendering an opinion, very deep strike, well centered and perfectly medal-aligned with the classic heart-shaped flan with requisite hole in stem, with two dates and all three mintmarks and assayers, even a part of the king's name and ordinal V. We are honored to usher this special piece into its next home in another world-class collection. NGC #6448837-001. Pedigreed to the Pat Johnson Collection (stated on label).
