The Swedish team, called the Ocean Explorer team, discovered the wreckage of a trade ship called the Jonkoping in 1997, as well as the ship’s cargo of extremely rare 1907 Heidsick Monopole Gout Americain champagne.

Millions were made by the Ocean Explorer team, as the bottles sold for approximately $13,000 each.

The extremely lucrative find has motivated Peter Lindberg, leader of the Ocean Explorer, as well as the rest of its members to keep up the search for underwater treasures.
