SS Gairsoppa was a British cargo steamship that was built in 1919 and sunk in the Battle of the Atlantic in 1941. 85 of her complement were killed, and only one person survived. When she was sunk, her cargo included 7 million ounces of silver bullion. In 2012 and 2013 a US company recovered part of the bullion, and in 2014 the Royal Mint struck 20,000 silver coins from it.
