Pure Silver Oval Coin with Japan Mint Assay Mark Manufacturer: Japan Origin: Japan Weight: 100g This is a replica of a Tenpo Goryo-ban (oval coin) made of pure silver, comes in a paulownia wood box. It has the Japan Mint's quality assurance mark for reliability and peace of mind. I purchased it from the long-established Ijima Kin-Gin Kogyo in Tokyo and have kept it unopened. It's perfect for collectors, and also ideal for asset management as silver prices continue to rise in real-time. Please refrain from price negotiations for this item. I apologize, but I will not be able to respond to price negotiation requests.
