This is a very early American coin silver napkin ring. The appearance is of a piece of cloth in a circular shape being held together by a button. Several pictures are shown to illustrate the ingenuity of the design. The United States did not adopt the sterling standard until late in the 19th century. Many items prior to that time were of sterling standard but not marked in any way. Coin silver items were not unusual in the 1870's and 1880's. These were made from melted silver coins and essentially were of sterling standard though were rarely marked. This napkin ring is fairly large with a height of 2 inches and a diameter of 1.75 inches. The only mark is shown in the last picture, a name on the "button," which appears to be Maggie. The napkin ring is quite heavy at 1.6 ounces o a postal scale. I have a second one identical to this except for the name.
