Watch List notes:

Mexico City, Mexico, cob 8 reales, 1715J, cut into heart shape, Pieces of Eight plate coin. S-M22; KM-47; CT-744. 21.39 grams. Bold full date, nearly full but oddly double-struck shield and cross, nicely toned and nearly corrosion-free, but main attraction is the edge-shaving, done in the 1700s to transform it into "heart" shape, which earned it a spot on a photo-plate in Kip Wagner's famous book, with credit to National Geographic Society (dated 1964) below the photo. It is hard to put a price on such a memorable, unique piece! Pictured (actual size) on the left-hand photo plate between pages 128 and 129 in Pieces of Eight (1966), by Kip Wagner. Recovered from: Spanish 1715 Fleet, east coast of Florida

Estimate: $5000 - 10000
