"A handful of Arabian silver coins found in New England may be the last surviving relics of history's most notorious act of piracy — and perhaps one of the most famous pirates who ever lived." Source: Live Science.
"Evidence suggests the distinctive coins were spent as common silver in the American colonies in the late 1690s by the fugitive pirate crew of Henry Every, also known as John Avery, who had fled there after plundering the Mughal treasure ship Ganj-i-sawai as it was returning pilgrims from the Muslim Hajj.
"Researchers aren't certain that the coins are from the Ganj-i-sawai, but their origin, their dates and their discovery in such a distant region suggest they were seized by the pirates and spent in the Americas."
According to the Muslim historian Khafi Khan, Every and his cronies inflicted "an orgy of horrors" on the people aboard the Mughal ships they captured. Some dispute this, but Kahn's account was backed up, at least in part, by the British governor of Bombay, Sir John Gayer:
"It is certain the Pyrates, which these People affirm were all English, did do very barbarously by the People of the Ganj-i-sawai and Abdul Gofor's Ship, to make them confess where their Money was, and there happened to be a great Umbraws Wife (as Wee hear) related to the King, returning from her Pilgrimage to Mecha, in her old age. She they abused very much, and forced severall other Women, which Caused one person of Quality, his Wife and Nurse, to kill themselves to prevent the Husbands seing them (and their being) ravished."

Every was supposedly the target of the first worldwide manhunt in history. After the spectacular heist several of his crew were captured, but Every himself vanished, perhaps living out the rest of his life in England or on some tropical island. The treasure was never recovered.
