Your first two photos with the pair of unknowns look like battery contacts. The big copper disk is probably just a big copper disk. Stuff like that I save to recycle-- copper and brass has some value.
It looks hand-cut and shaped whatever it is.
Its thicker than normal copper sheeting.. Maybe it's just left over from cutting a hole in something else..not sure.
There's Native American history in the area the first thing that actually went through my mind was that it was some piece of copper traded to the natives.. that they made something out of but that might be just fanciful thinking it doesn't quite have the patina to be that old I don't think.
Thanks man.
Those do look like the old garter snaps women used when I was young. Great finds you've made. Thanks for sharing the pics with those of us in the frozen northeast.
