Does anyone have any idea what this could be? I was hiking along a trail near Put-in-Bay, Ohio. It was bent up but I straightened it out. I have no idea what it could be. It is copper and has two pins on the back about .75” long. Maybe to pound into wood? It has a cross ingraving in the lower left corner and a weird inscription on the upper right hand corner. See pics. Any help would be appreciated, thanks
