Went back to the a yard where I found all 7 silver coins one last time. Was up by an old tree and dug down two inches and found a small button. Got home and cleaned it off and it is an eagle with a anchor under it surrounded by stars. Looked it up online and found a match and it is a civil war button. Live in Indiana and not expecting hat.Can see the Ohio river from the hunting site. It is right over the hill. Also found a Hickok buckle with 1939 on the front. No idea what it is for.
