1 Pitis - Mansur

The Sultanate of Kelantan occupied an unusual political position in the late nineteenth century, nominally a Siamese vassal while maintaining its own monetary tradition in tin — the metal that defined commerce across the peninsula. This pitis was struck under Sultan Muhammad IV, whose reign saw Kelantan's gradual absorption into the British sphere formalized just a decade later under the 1909 Anglo-Siamese Treaty, which transferred suzerainty and effectively ended independent Kelantanese coinage.

Tin pitis from this period are frequently found with surface corrosion and casting irregularities, a function of local production methods rather than post-mint damage.
