Searching an old park in Albany NY I got a very deep signal digging down about a foot, I pulled out what looked like a piece of copper plate, which I happen to find a lot of this in n the park. When I inspected it I happen to see an eagle under the dirt, I flipped it around and saw a tung and knew what I had, after doing some research turned out to be an 1874 federal saber belt plate.
