Watch List notes:

Potosi, Bolivia, cob 2 reales Heart, 1733E, unique, NGC AU 50.S-P46; KM-unl; Cal-870.6.89 grams.This lovely piece bears the distinction of being the first (and, for now, the only) numerically-graded AU Heart at NGC, and it is well deserving, as all of its deeply impressed interior design is full and well detailed (albeit with doubled cross) and devoid of any significant wear or marks, plus the fields are graced with a rich old toning that attests to its unmolested history, the hole in the stem at top now accurately considered to be a part of the piece's original manufacture. Per the period, there is not much legend visible, although this coin does show a nearly full king's name. With well-formed stem, shoulders and tail, this piece reflects the classic shape intended for these amulets whose purpose was tied to the Catholic Church starting in the 1690s when the Sacred Heart of Jesus became a popular symbol in Europe and abroad. This piece is also currently unique, as the only other known 1733 2R Heart is assayer YA (Coin Galleries auction of July 1975). Any Heart is a rare beauty and an opportunity to acquire one should not be taken lightly.
