Thetis, sunk in 1830 off Cabo Frio, Brazil

The English Navy vessel H.M.S. Thetis was on a trading trip, returning from Rio de Janeiro with 800,000 dollars on board, when her bowsprit struck a cliff off Cabo Frio and she was dismasted, after which she drifted along the coast and finally foundered in a small cove. All hands were rescued, and three-quarters of the treasure was soon salvaged, followed by another nearly 150,000 coins by the summer of 1832. What little remained was recovered in modern times.
