A small silver coin about the size of a nickel, struck in Boston in 1652, set a world record on Tuesday, November 19, as it sold $2.5 million at a Californian auction house.Stack’s Bowers Galleries said the coin was discovered in an old cabinet in Amsterdam around 2016 and the owner only recently decided to research his find.The coin is thought to have come from the Quincy family of Boston, a political dynasty that included Abigail Adams (nee Smith), the wife of John Adams, who was ambassador to the Netherlands in the 1770s and 1780s, and later the second president of the United States.The piece surpassed the previous record price of $646,250 for an American coin struck before the revolution, according to Stack’s Bowers Galleries.
