In Canada, you can get two loons that are almost worth half a dollar in real money.
But, if you cross the Great Lakes often enough; invest your coins carefully enough (like the old pirates did) in the Caribbean off-shore island banks, over time, interest will double their value in your estate.
But this is a justice a case of hurryin' your herons across Huron so your heirlooms can begin doublin' your doubleloons investing doubloons.
