Between the end of XVI Century and the beginning of XIX Century Potosi minted vast quantities of silver that was extracted from Cerro Rico. Among the millions of silver coins minted in Potosi during the colonial era, a few were struck on blanks with the shape of the Sacred Heart. These are known as “Potosi Hearts” or “Heart Cobs”. They were all struck at the beginning of the XVIII Century and the reason why reminds a mystery. Glenn Murray considers that silver dealers asked for these coins to be later on sold to important clients.
Potosi never made gold hearts, so there is no coin superior in value for those interested on Potosi coins or the countless collectors of crown sized coins all around the world. This implies a huge demand for this coin, which guarantees high price; its rarity makes its price very difficult to predict.
