Odyssey Marine Exploration announced the excavation of major shipwreck treasure.

The deep-sea treasure hunters recovered over 500,000 silver coins weighing more than 17 tons, hundreds of gold coins, worked gold, and other artifacts from a 1700 shipwreck at an undisclosed location.
It is believed that this recovery constitutes the largest collection of coins ever excavated from a historical shipwreck site. "The remarkable condition of most of the first 6,000 silver coins conserved has been a pleasant surprise, and the gold coins are almost all dazzling mint state specimens." said Greg Stemm, Odyssey's Co-founder. "We are excited by the wide range of dates, origins and varieties of the coins, and we believe that the collecting community will be thrilled when they see the quality and diversity of the collection."

There is still more treasure to be recovered, that is why the location is kept secret.
