1 Cash - Yuanfeng Tongbao, Tin imitation

Tin cash coins of the Malay peninsula were produced locally to fill chronic shortages of Chinese copper coinage, which dominated regional petty trade but arrived irregularly and in insufficient quantities. The Yuanfeng reign period (1078–1085) lends this piece its inscription, but the coin itself was almost certainly struck well after that era — possibly centuries later — by peninsula traders or small-scale founders who copied the legend for its commercial familiarity rather than any claim to imperial authority.

Tin was the obvious local substitute, mined abundantly across the peninsula, particularly in the Perak and Kedah regions.
