This is an antique liqueur glass from around 120 to 150 years ago. There are no hallmarks, but it appears to be around silver 925. You can tell by the texture and the grooves that it is not nickel silver or silver-plated. The contrast between the aged, darkened silver and the silver itself is cool. This is definitely a piece for enjoying chilled sake. There appear to be no particularly noticeable scratches. Diameter: approximately 4.5 cm, Height: approximately 5.7 cm.
