I have a vintage Native American money clip. It is a silver tone metal eagle head inlaid into green wood or stone. It has grain like wood but is really hard like stone. The main part of the clip is also metal. It is 1 3/4 inches long and 1 inch wide. I didn’t see any metal content markings so I took it to a refining company. They used lasers to check it and said it is copper, nickel and zinc. See my other ads for jewelry, artwork, home decor and more.
