Wayne and I went back to the Union Fort yesterday and hunted a field in back of the fort. We could see bits of brick, pottery, glass, ect. on the ground and Wayne has found some flat buttons in the area in the past. Old, old house site. We hunted slow in the area and in two hours of hunting each of us had a piece of silver Spanish coin. My piece was worn smooth with nothing on it but the piece Wayne found had the date on it and it was very clear. It had 1723. Now that's getting close to 300 years old. I had two pieces in my collection I had found in the Suffolk area and Wayne has serveral. Here's some reading about what the American colonist used for money.
