I found this copper item at an area (not the beach) with over 150 years of recorded history. It was down pretty deep in the turf (9 inches or so). Seems to be a tip of some sort, but, any input would be welcome. It's hollow and tapered on the big end, and has a slotted hole on the small end. The holes don't connect. Initially, I thought maybe the tip of a fishing pole, but, I've never seen one with this design or one made of copper. There's two small grooves around the big end which makes me think it was something more decorative than something industrial. The first two photos are as found and just washed off. The last is after I cleaned it up a bit. Thanks.
