I can't think of any New England gold coinage from the 1700's, most of it wasn't gold, and what was gold wasn't made by the colonies/states.
The History Channel did some stuff about that subject. I believe we took our own sweet time getting the U.S. Mint off the ground. It was nigh on the mid-nineteenth century before we had enough of our own coinage that we stopped accepting spanish reales and british shillings.
