Tin cash coins of this type circulated across the Malay peninsula as locally produced imitations of Chinese Song dynasty cash, manufactured to fill a chronic shortage of small-denomination exchange currency in regional trade networks. Chinese copper cash was actively hoarded or exported, leaving tin — abundantly mined in the Malay states — as the practical substitute. The Jingyou Yuanbao prototype dates to the reign of Emperor Renzong, 1034–1038, but these Malay tin pieces were struck well beyond that period with no pretense of official sanction.
