This is a pure silver sake cup. It was kept in a chest, and as it was stored by a non-professional, the condition is as shown in the photos, with some stains. Please understand. It seems to be something that was distributed by the local government to celebrate the 88th birthday. I believe the quality is not an issue. I will be selling it based on the price of silver and its weight. - Shape: Circular - Material: Pure Silver 67.69g - Engraving: 建 (Ken) - Engraving: 純銀 (Pure Silver) Pure Silver Pure Gold Thank you for viewing.
