业复五铢钱

The fourth line of 刘禹锡's 蜀先主庙, after 势分三足鼎 'he split the realm like the three legs of a cauldron'. The five-zhu coin, first cast under 汉武帝 in 118 BC, stood for Han rule: 王莽 abolished it when he took the throne, and the Eastern Han brought it back in AD 40. Restoring the coin means restoring the Han, which 刘备 claimed to carry on in Shu.

业 here is a life's work or cause, and 复 means 'to restore'. 铢 was a unit of weight, a twenty-fourth of a 两, and the coin bore its weight, five zhu, on its face.
