2 Keping - Lotus-Malay inscription Trumon/Thailand Pattern

This coin is a mule, with the observe inscription using Thai numeral, but with reverse inscription in Arabic Malay script referring to Trumon, a region located near Aceh, Sumatra. 

These coins were not official currency of any state. They were first issued in the early 1800s by British merchants at Singapore, to alleviate base coin shortage, before spreading to various parts of the Malay Archipelago. To circumvent confiscation attempts by colonial authorities (particularly the Dutch), British merchants use inscriptions that refer to locations that are vague, fictitious, or unaffiliated to Europeans. In this manner, legally it could not be argued that the tokens were intended for circulation in colonial territories.
