![]() We Buy Sterling SilverSterling silver can be one of the most confusing items to figure out-is it Sterling or is it plated? Many items have either "Sterling" or "925" stamped on them to indicate that they are in fact Sterling silver. But many items do not. The best way to find out which of your items are valuable silver is to bring them in. With our years of expertise, we will examine and, if needed, test your items to determine if they are indeed silver. We will make an offer to you on those that are silver. From there, it's up to you. So bring us your tea sets, flatware, and other items and we'll go to work for you! Contact us today. ![]() |
