Sterling silver contains a little over 7% copper and silver plate often has a base of copper or an alloy containing copper. Copper corrosion and some copper salts are green, as in the popular verdegris patina on outdoor copper scupture or roofing. I have found green corrosion on some of my silver plate, which I believe is copper sulfate and due to the reaction of sulphur compounds (found in many foods and also found in newspaper, so don't pack silver in newspaper!) with copper exposed by the wearing away of the silver plate.
What else can I help you with?
Does silver turn green?

What makes sterling silver tarnish?
exposure to substances which react with the surface of the metal, usually sulphur. Sterling silver is .925 (925%) pure silver. The other .75 is made up of an alloy consisting mainly of copper which oxidizes over time. When copper is exposed to oxygen, it darkens and eventually turns green. Sterling silver doesn't usually turn green but will turn almost black if not protected. Fine silver or .999 silver doesn't tarnish. Argentium silver is a new type of sterling silver that is tarnish-resistant. Only certain chemicals will tarnish Argentium but it will not tarnish from oxidation. Some metals that contain little to no silver are branded with names that make it seem like real silver. One of these metals is nickle silver, which doesn't contain any silver at all.

Why is silver tea getting green with tarnish over time a chemical change?
Silver tea gets green with tarnish due to a chemical reaction between silver and sulfur compounds in the air, forming silver sulfide. This process alters the composition of the silver, resulting in a new substance with different properties. Unlike physical changes, which do not affect the chemical identity of a substance, tarnishing is irreversible and signifies a chemical change. Thus, the green tarnish is a clear indication of a chemical transformation occurring over time.
