Why did the Southern Han issue lead cash coins?

The first series of lead cash coins attributed to the Southern Han kingdom bore the inscription "Kaiping Yuanbao." This inscription is closely associated with the kingdom's founder, Liu Yin, who established the dynasty.

The issuance of these coins is speculated to have been a commemorative gesture, marking an important event or period during the Liang dynasty. The coins, therefore, become a tangible link between the two dynasties.

The Southern Han kingdom, renowned for its cultural and economic prosperity, also left a legacy in the form of currency.
