Lovely pair of coasters- wider size so should fit bigger bottles (magnums) as well as stands size champagne, wine or spirit bottles. They are copper ( small ding in one as shown in pics) with white metal grapevine decoration to the edge. The grapevines do have signs of wear, some areas are quite smooth from polishing. I have estimated the age as there are no makers marks to help identify these, so arts and crafts is a best guess and they could be newer or older than that!
