In 2007, the Odyssey Marine Exploration American company found about 500 thousand gold and silver coins at the site of the sinking of the Nuestra Senora de las Mercedes Spanish frigate. This ship sank near the southern coast of Portugal in October 1804 during a battle with the British fleet at Cape Santa Maria.
In February 1941, the SS Gairsoppa British steamer, which carried tea, cast iron and silver from India to Britain, was torpedoed by a German submarine. The ship sank 300 kilometers south-west of Ireland. More than 70 years after the shipwreck, in 2012, about 1,200 silver ingots (one-fifth of the cargo) were raised to the surface and another 1,500 in the following year. It is assumed that there were in total up to 200 tons of silver on board of the ship.
In April 1912, in the northern part of the Atlantic Ocean, more than 600 kilometers southeast of the Canadian island of Newfoundland, the Titanic steamer wrecked. At that time it was the largest ocean liner with 2,208 people on board. The ship was packed with artifacts and treasures, including diamonds, gold bars, silver and other jewelry, as most of the passengers were wealthy people. The cost of sunken wealth is estimated at about 200 million dollars.
In 1865, during a hurricane off the coast of the State of Georgia, the SS Republic US vessel sank, which carried coins for a total of 40 thousand dollars. More than 51 thousand gold and silver coins of the USA, as well as about 14 thousand artifacts, were discovered at the shipwreck site more than 130 years later. The cost of the treasure found on the ship is approximately 180 million dollars.
