I don’t like the hole so high up for some reason, was thinking it was some attachment to a lock plate or pocket knife or something but, that said, it is possible it was re used as a point, I’m not sure there’s any way to prove it though
The hole seems very regular for an ancient artifact, like it was drilled or punched by machine. But I'm no expert on copper artifacts, so that's just an observation.
That hole looks too perfect. I’d expect it to be more crudely if done in the wild. Unless the crafter used part of a pot or kettle that already had a hole in it from the manufacturing process.
