Thank you for viewing! I'm a collector fascinated by the charm of copper coins. This is a 1-ounce coin, 999 pure copper. It has a diameter of 4cm and weighs 30g, with the characteristic depth of copper, shining with a subdued luster. Being copper, it doesn't react to magnets. It will be shipped in a coin case. It's as shiny and beautiful as a proof 10-yen coin, but it will quickly tarnish and lose its shine if not stored properly. I was disappointed because I initially tarnished dozens of them. I don't just want to sell and be done with it, so I'll also share maintenance methods to help you keep it shining and take good care of it. Also, I handle them with gloves to prevent fingerprints, and I carefully inspect each item. I strive for pleasant transactions. I also have various other items for sale, so please take a look. ↑ Click here for my coin collection. ↑ Click here for my copper coin collection. ↑ Click here for my collection.
