WARWICK, R.I. (NEXSTAR) — A handful of 17th-century Arabian silver coins unearthed across New England may help solve one of the planet’s oldest cold cases.

Amateur historian and metal detectorist Jim Bailey found the first intact coin in a Rhode Island orchard and discovered it was minted in 1693 in Yemen.

Other coins have turned up in Massachusetts and Connecticut, and Bailey has found documents tying them to legendary English pirate Henry Every, dubbed the “King of Pirates” by his contemporaries.

The murderous pirate became the subject of the first worldwide manhunt after plundering an Indian ship carrying Muslim pilgrims home from Mecca.

According to historical accounts, his band tortured and killed the men and raped the women aboard the ship, a royal vessel owned by Indian emperor Aurangzeb.

During the raid, he stole $108 million in precious metals and jewels, making him the richest pirate in the world.

It is believed that he escaped to the Bahamas, but where he ultimately ended up is unknown.

Bailey and other historians say the discovery of the coins is evidence that Every, who was never captured, hid in the American colonies for a time.
