600 Cash - Wang Mang (Third reform)

The 600 cash coin was minted in 10 AD during the brief Xin dynasty, established by the usurper Wang Mang. Following his rise to power, Wang Mang instituted a series of radical currency reforms aimed at consolidating state control over the economy and purging the influence of the preceding Han dynasty. This denomination, known as the Da Quan Wu Shi, was part of a complex system of multi-denominational coinage that ultimately struggled to gain public trust.

The design of these coins represents a significant aesthetic shift from the traditional round coins of the era. The characters are rendered in a distinct, elegant style often attributed to the calligraphic standards promoted by Wang Mang’s administration, known as the 'iron seal' script. While the artistry was sophisticated, the high face value and the aggressive economic policy behind them caused widespread financial instability, leading to the eventual abandonment of these issues following the collapse of the Xin dynasty.
