China, Northern Song Dynasty, Emperor Zhezong, Iron Cash Coin

These iron cash coins were issued during the Northern Song dynasty under Emperor Zhezong (r. 1085-1100). Most Chinese cash coins at this time were cast in copper, which is what makes these issues unusual. The Song economy had grown so large by the late 11th century, that copper was in short supply. In response, the government expanded the production of iron coinage. However, the government became anxious about the outflow of iron currency into the Liao Empire and it’s potential use to be melted to make iron weapons; as a result, iron currency was ordered to be alloyed with tin during the smelting process.

The obverse carries the four-character inscription while the reverse is blank, as typical for Song cash coins. Iron issues often appear heavier and darker than copper coins and frequently show rougher surfaces due to the metal and casting process. 

Each includes a Certificate of Authenticity and is guaranteed genuine.
