The Federal standard in the silver coating is QQ S 365D which covers electrolytic silver plating over various types of metals. The finish can be either bright semi bright or matte. The brightness of the finish can still depend on the original surface finish of the base material so you might not get the same finish on different products that use diverse materials.

Iron is much more susceptible to corrosion so it is important to identify it. Nickel is often found in alloys or as a plating layer. For example nickel silver also called German silver is a white metal alloy that contains no silver it usually contains copper nickel and zinc and can therefore be identified with a spot test for nickel.
