Is there a list of what exactly was lost? Does anyone actively seek out and salvage this sunken treasure? I hate to think of another Garfield Phone thing in the future with something more dangerous.
In the 1990s, a ship from Hong Kong bound for Tacoma, Washington lost a shipping container that was filled with 30,000 yellow duckies.
Oceanographers were able to collaborate with beachcombers in the western US (and eventually as far away as the UK) to validate their models of how the currents would move the ducks.
This ship [0] went down offshore of Cornwall in 1641, with 60 men, 100,000 pounds of gold and 500,000 pieces-of-eight aboard. Cornwall is not known to be friendly to wrecks. And yet, nearly 400 years later, she's not been found. They say.
In the UK there is some dispute about 'finders keepers' in any case, there was a case last year where a couple of guys got jail time for stealing a hoard
