Thank you for viewing this item.
This is a Japanese ceramic 1 Sen coin manufactured in 1945 (Showa 20), near the end of World War II. It is listed as KM#110.
Due to wartime shortages of copper, aluminum, and other metals, the Japan Mint commissioned private ceramic manufacturers to produce coins from fired clay. Approximately 15 million ceramic coins were manufactured at facilities in Kyoto, Seto, and Arita.
Although mass production had begun, these coins were never officially issued because World War II ended before they could be released. Most were subsequently destroyed, but some examples survived and are now known as Japan’s “phantom coins.”
Although commonly called porcelain coins, they were made from a specially prepared mixture of clay and mineral materials. Their color varies from bright red to dark brown depending on the firing conditions.
