1 Cash - Tonghe Yuanbao

The Tonghe reign period of Emperor Shengzong lasted nearly three decades, but coinage bearing this era name was produced inconsistently, and surviving examples vary considerably in casting quality — a reflection of the decentralized mint operations typical of Liao monetary administration. The Liao, as a Khitan state, adopted the cast-bronze cash format from Tang and Song China while maintaining parallel economies in which silk, silver ingots, and livestock functioned as primary exchange media for many transactions. Bronze cash played a secondary role in commerce compared to its Chinese contemporaries.
