The Schmitt family retrieved 51 gold coins from a shipwreck, along with a 40-foot ornate gold chain and a special coin believed to have been created for King Phillip V of Spain.

The plunder has been valued at $1 million (£638,000) and was discovered on a ship which sank in 1715 while en route from Cuba to Spain.

Brent Brisben, a spokesperson for the 1715 Fleet - Queens Jewels LLC, said: ''The treasure was actually found a month ago.''

But keeping the news quiet has been ''particularly hard for the family that found it. They've been beside themselves.''
