The Japan Mint is issuing the most extensive and beautiful series of coins in its history commemorating 47 Prefectures.
The large Prefecture 40 mm coins are being minted in gem proof quality from 99.9% pure silver, limited to 100,000 of each, and picture local scenery in full color.
Chiba is featured on the newest Prefecture coin. The Chiba coins obverse depicts the Tokyo Bay Aqua-Line and Nanohana Mustard Flowers. The Tokyo Bay Aqua-Line is a 15.1 km toll highway opened in 1997 that links the Chiba and Kanagawa Prefectures. It is known as a scenic tourist attraction, and features 360 degree views of the sea. The Nanohana Mustard Flowers are also featured on the coin, and are familiar to many as the official flower of Chiba, chosen as such in 1954. Official American distributor Panda America offers these in original government packaging with a Certificate of Authenticity.
Earlier issues in the Prefecture Series, that was launched in 2008, are still available from Panda America.
