The currency circulation in the Three Kingdoms period was different from the silver and copper coins usually used in costume dramas.

Silver was not used as currency in this period. At that time, the monetary situation was very chaotic, and the credit of metal currency was not high. The common currency of Shu is generally "Zhi 105 baht", and the so-called "Zhi 105 baht" does not mean a dollar value 100 baht, but 500 baht. During the Three Kingdoms period, more physical exchange was adopted. Cloth, grain, salt and even population can be exchanged.
