1 Cash - Xianping Yuanbao, Tin imitation

These tin cash pieces were produced locally on the Malay peninsula as substitutes for Chinese copper cash, which circulated widely across Southeast Asian trade networks but were chronically undersupplied. Tin was the obvious local substitute — the peninsula sat atop some of the world's most accessible tin deposits — and these imitations filled genuine transactional gaps rather than functioning as counterfeits in any fraudulent sense.

The Xianping reign spanned 998–1003 AD under Emperor Zhenzong of the Song dynasty, though the Malay imitations were almost certainly struck well after that date.
