@c5news: Treasure has been recovered from an 18th century Spanish galleon, dubbed the “holy grail of shipwrecks.” The ship is believed to hold 11 million gold and silver coins, emeralds and other precious cargo from Spanish-controlled colonies, which could be worth billions of pounds. The San José lies 600m (almost 2,000ft) below the Caribbean Sea, but its exact location is a state secret, and ownership of the treasure is hotly contested. Scientists have stressed this trip was purely for historical research. #treasure #shipwreck
