Although you can always have the object replated, this will inevitably reduce its value. American Silver Centerpiece, Gorham Mfg. Co., Rhode Island, 1903. However, it's wise to rely on an expert to restore any effects the metals structure. This includes replating, straightening bent areas, smoothing dents and bruises, and soldering holes or splits.

Silver is unavoidably prone to certain chemical reactions, especially tarnish and corrosion.
Simple precautionary care and storage can greatly reduce these reactions. To avoid tarnish, corrosion or salt damage, wash your silver with gentle soap and water after each use, dry it, and wrap it in acid-free tissue paper. Place the wrapped silver in a tarnish-retardant or plastic bag but not in plastic wrap, which clings to the metal. If you leave your silver out for months at a time, you can treat it with a tarnish-retarding lacquer. Lacquer is not recommended for silver that you eat with or out of.
