Mid Century Modern Sheffield Silver Champagne Or Wine Coaster Formica USA

Mid Century Modern Wood Grain Formica Laminate Made in the USA for The Sheffield Silver Vintage Sheffield Champagne Or Wine Coaster Formica Faux Wood The metal part is silver in color but is NOT silver I can not find any hallmarks on the metal part. Lots of tarnish , scratches and digs consistent with age and use see last 6 pictures and video for closer look at flaws. ~ 5 diameter and ~ 1.5" deep ruler in pictures above, questions are always welcome. Needs some metal polish to take away the tarnish. If you use metal polish then I would only use wrapped candy in this piece if using as a candy dish ... always concerned about chemicals leaching into my food. Would make a nice accent to a mid century modern bar I have used it hold my pearl necklaces ( faux pearls and fresh water pearls I am not rich to own real pearls LOL) could use it as a catchall for change and keys at your door or a men's caddy to hold wallet, cuff links , watch. Or even a desk accessory to hold paper clips etc.
