A large cache of $170,000 in British gold coins was buried in the early 1800s along the banks of the Parker River in Byfield, Massachusetts. Legends say that it was buried within sight of a large boulder marked by a chiseled "A" six inches high.
The Lost Treasure of Plum Island
In the 1960s a former German claimed that he was dropped off at Plum Island, Massachusetts, in 1943 to perform sabotage in the U.S. Due to bad weather and other foul-ups he was the lone survivor on the beach where he hid a box,containing $200,000 in U.S. currency, on the Atlantic side of the island. He then abandoned his Nazi-laid plans and took up residence in Wisconsin, later becoming a U.S. citizen. He made one attempt many years later to recover the cache, but it was never located.
