undersea treasure

Gold and silver and emeralds were taken from shipwrecks centuries ago worth up to 450 million USD (10.2 trillion dong).

During the flight into orbit, NASA astronaut Gordon Cooper is said to have drawn treasure maps in the Caribbean Sea and kept it secret for over 40 years.

A large treasure of 300-year-old pure silver bars, each weighing more than 36kg worth nearly $ 80,000 has been found by a group of treasure hunters on the seabed.
