Watch List notes:

Potosi, Bolivia, cob 1 real Heart, 1734 E, very rare, NGC VF 25, finest and only example in NGC census. S-P46; KM-unl; Cal-550. 3.25 grams. With rich old toning and evident wear, including within the hole that got larger with use, this piece was surely a religious talisman for a long time, and in fact this is its first appearance on the market so far as we can tell (as it is not the Americas/Karon example nor the one in Calico's 2008 edition), its appeal for long use no doubt due to its classic shape with large stem and perfect medallic alignment with a second date neatly tucked into the tail.
($3000-4500)
