Watch List notes:

Clump of four small silver cobs embedded in a large chunk of debris. 158.56 grams, 2-1/2" in diameter. Cupcake-sized (and -shaped) clump of oxidized iron (lots of green over brown) with four solid cobs sticking out one end, all probably Potosi 1R, one of them at a right angle to the others and more embedded, the other three sandwiched together and showing 1677 date on one of the outer coins and 1666 date on the other, both darkly toned but apparently solid and uncorroded, a great display overall, one of the biggest clumps we have seen from this wreck. Consolacion, sunk in 1681 off Santa Clara Island, Ecuador

Estimate: $350-500
