Crimp ring for poly plumbing pipe.
All my copper finds in the water, are under beach sand, and have no oxidization, or little to none. The land finds are HEAVILY hard mud caked and green. If you search my copper cache post, all of those finds were found where this ring was found.
a little research on the internet would tell you a lot
