A museum in North Carolina plans to exhibit a collection of coins that were found on the Outer Banks. The coins date as far back as 221 BC and originated in places as far away as Spain and Egypt. The Virginian-Pilot reported Monday that the 55 coins are currently kept in a back room of the Graveyard of the Atlantic Museum. Depending on state funding, there are also plans to create an app that displays each coin and the history behind it. The late William Sell and his wife, Catherine, of Pennsylvania collected the coins over decades. Some could have been lost in a shipwreck, separated from pirates’ loot, or left as part of a ship’s ballast.
