10 Keping - Zainal Abidin III

Trengganu's tin coinage of the late nineteenth century occupies an awkward historical position — the sultanate was nominally under Siamese suzerainty while simultaneously resisting British pressure to accept a Resident, a standoff that lasted until the 1909 Anglo-Siamese Treaty finally transferred suzerainty to Britain. Zainal Abidin III ruled through all of it, and these locally-cast tin kepings continued to circulate alongside Spanish, Mexican, and Dutch trade coins in a currency environment that was, by any measure, chaotic.

Tin was the obvious material choice given Trengganu's proximity to the ore-rich west coast states, though it was never the prestige metal that gold and silver commanded regionally. Singh's documentation of this type remains the primary reference, with die and casting variation between examples common enough to complicate strict attribution.
