Went on a hunt in my back yard and found a bunch of things so far. Mostly pottery and cool stones which may be arrowheads, but below I was not able to identify as of yet. The top item seems to be a broken horseshoe, but please let me know your thoughts on all 3 pieces. My area had several civil war battles close by, as well as a heavy Cherokee Indian presence. All pieces are are a heavy metal, assumed to be iron.
