I own a 19th century koummya, brass scabbard with very worn silver accents in front, the silver plating is attached on a layer tin or similar metal. The same effect you can notice by the koummya in question. I guess it was done to let the silver look thicker. A test would show that in up is silver where it is not worn, believe me, it gets dark like I know it only from silver. But you are correct, under the silver is something similar to tin.
