MEXICO, Mexico City, encrusted cob 8R "biscuit," king not visible, date and assayer not visible. 27.29 grams total. Scarce as an uncleaned "biscuit" from this wreck. Almost completely encrusted with just a sliver broken off to reveal a very dark coin inside, some bits of shells, sand, pebbles, and rust sticking out on one side. Pedigreed to the Steve Valentine Collection, with original certificate from the salvor/conservator. Recovered from: Joanna, sunk in 1682 off South Africa
