Pahang Tampang One  Sixteenth Dollar Tampang 1235 A.H. (1819).
Rarity:Unique/Unlisted
The development of the "Tampang" (Tin Hat Money) was based on the earlier Pyramid or Pagoda-shaped tin ingots currency which was cast in the neighbouring State of Perak and Selangor. Thwe Tampangs were shaped into four-sided pyramid with a flat top and a broad foot or plinth. These early Tampangs were cast in the hardened sand moulds and are rather rough in manufacturer. The intrinsic value of the early tin Tampangs determined their face value.
The earlies known Tampang of Pahang was dated 1325 A.H.(1819) and was issued in the reign of Bendehara Sewa Raja Tun Ali. According to Mr. Saran Singh's book "The Encyclopaedia of The Coins of Malaysia Singapore and Brunei 1400-1967", the first issue was equivalent to $1/16 (One Sixteenth of a dollar) or approximately six (6) Cents of the Spanish silver dollar (8 Reals).
And it was recorded in  1846 new improved Tampangs, which were casted in a brass mould,were issued with the value of $1/25 (One Twenty Fifth of a dollar). These were equivalent to 4 Cents of the Spanish or Mexican silver dollar. The top of some of these tampangs had the mangosteen rosette design which may have the mint mark of the place of manufacture. These Tampangs were hollowed out in the centre which gave them a hat-like shape and were sometimes refered to as "tin hat money". These Tampangs were slightly in size and their intrinsic value bore little relation to their actual worth. They thus came to resemble a token form of currency.
A hole was pierced in these Tampangs so that they could be tied together with a string or thong to the required amount. As an example of the $1/25 Tampang were equal to one Spanish or Mexican silver dollar.
