Coins marking Forbidden City's 600th anniversary to be released

Three rectangular coins use the "three great halls" on the axis of the Forbidden City -- the Hall of Supreme Harmony, the Hall of Central Harmony and the Hall of Preserving Harmony -- as decorative patterns on their tails sides. A total of 300,000 coins of each type will be released, together with 2 million 2-yuan silver coins with the Chinese auspicious mythical animal kylin on their reverse.

All of them are legally tendered coins in China.
