I went out again today to where I found the Mass copper yesterday. If my hopes are correct, I think I found a Nova Constellatio!! It's got the rays and stars, but on the back all I can see are the letters RN I think. It looks like there are other possibilities like some sort of Vermont coin, too.
All I've done is a light brushing; I don't want to mess things up like I think I did with the Mass cent. Any help with an ID would be appreciated.
