Too nice of a morning to not search. I found quite a few square nails and wire. I did find this American Eagle head stamp. The gauge is gone, but appears to be 12. I find they began producing these in 1922 and I find no “last produced” date, so far. I also found a non-ferrous reed plate. Either a harmonica or music box. Seems pretty thick. I’m guessing a stiffener/backer plate for a harmonica reed plate. The 3rd item is a possible artifact I found while digging. Will post it on Rocks forum.
