Record wreck found off Cornwall
A record haul of half a million silver and gold coins from a 17th Century shipwreck may have been found just 40 miles from Land's End, UK, an expert said. US treasure hunters said the coins, worth an estimated $500m (253m pounds), were recovered in the Atlantic Ocean. But Odyssey Marine Exploration, who described it as the largest find of its kind, refused to pinpoint the location.
