I: went to the homesite where I found the 2 and a half dollar gold coin the other day. Got a 177 signal loud and dug it up. About 3 inches i dug up a coin the size of a nickel.It was brownish color instead of black, so I knew it wasn't silver. I hadl no idea what it was, but it was thin, and I hoped it was not an old foreign coin.. l came home when I got through hunting without finding anything else of value. That's the way it has been at this place. Very few coins and only 3 copper memorials and an older clad quarter.Lots of trash, but the GT keeps finding signals, even though most are junk or brass, etc, Every weird noise the GT makes, I realize that's another target I haven't heard before. Anyway, I went to my coin book and matched the size of the coin in the book and I'm sure it's a half cent. Put a microscope on it at work, but nothing. I'm shocked at finding something this old there, but am really happy finding it. I just wish I knew what date it was. These coins were made from 1793 until 1857. HH-Mark
