Thank you for viewing. This is a pure silver sake cup, with a "silver" hallmark on the bottom. The paulownia wood box is marked "Made by the Japan Mint," and a paper from the Mint is also included inside. My father-in-law, who was born in the Taisho era, appears to have received an award from the Fire and Disaster Management Agency. When I asked my husband, he didn't know when it was received. It has been stored for many years, so there is some age and soiling. Please understand. #PureSilver #SilverCup #FireAndDisasterManagementAgencyAward #ShowaRetro #Antique #Crafts
