1 Cash - Shaosheng Yuanbao, Tin imitation

These tin cash imitations circulated widely across Maritime Southeast Asia as a practical substitute when genuine Chinese copper cash was in short supply — a persistent problem given the region's near-total dependence on imported coinage for small transactions. Local rulers and merchants alike sanctioned their production, and tin, abundant in the Malay Peninsula and Bangka-Belitung, made it the obvious material of choice.

The Shaosheng reign spanned 1094–1098 under Emperor Zhezong of the Northern Song. Why that particular reign title was chosen for imitation, centuries after the originals, likely reflects nothing more than the availability of a worn prototype in a trader's purse.
