Watch List notes:

Potosi, Bolivia, cob 1 real Heart, 1718Y, extremely rare, encapsulated NGC VF 30, ex-Newman (stated inside slab). S-P43a; CT-1621; KM-unl. An attractive example of the classic Heart shape, as made and worn for religious use as the Sacred Heart of Jesus Christ, this specimen with rich old toning and decent strike (the pillars slightly doubled, the full cross with date in strategically placed tail), typically holed in the stem, and with excellent pedigree. Like most Heart minors, this specimen is probably unique. Pedigreed to the Eric P. Newman collection (Heritage auction of January 2014, lot #30363). ($7000-10000)
