It's a cigarette or card box, made for export. I can't find that mark off hand but I would think it dates to the late 1800's/early 1900's. It would be termed "Chinese export silver". The mark, if identified would more than likely help put a date on it. It's a popular design with the repousse dragon coming out of the sea, nice water motifs on the sides. Not as detailed and elaborate as some but it looks like a quality piece. I like it.
