In my post I guess it wasn't clear that I thought these were un plated planchets. If the plating was removed, the surface wouldn't be as smooth. The surface looks like what you would have if there were no copper plating. If it was mercury rubbed, it would be a mirror surface. I don't remember who it was, maybe Silvio said that mercury rubbed coin will return back to copper with age. All I know is they were shinny for as long as I kept them back in the 60s.
