Old Brunei Coins
The third form is the 'Duit Besi' or Iron Money. This is really true iron money as in those days iron was so valuable that it is used as money. One hundred flat pieces an inch square are so valued at a dollar and among the poorer classes, these iron pieces form the function of coins. It was also found that these iron pieces were cut at their own discretion. This was used throughout the 19th century.
The fourth form of currency is the 'Duit Bintang' or Star coin. This is made out of copper and was minted in Birmingham for the Sultanate in 1887 (1304 Hijra). This coin was taken out of circulation with the introduction of the Straits Settlements currency.
Despite the introduction of the Straits Settlement currencies, the previous local monies were still used with peculiar exchange rates in the earlier days. All the coins were called 'paku' or piece where 4 pakus make 1/2 cent and 8 pakus make one cent or one 'kayu' (sakayu). As for the iron money, 3 penggals or 3 metal pieces make one paku and 3 ela besi panjang or 3 yards of uncut iron make one kayu.
Other words which were being bandied and were widely used in Brunei customs in those days include terms such as sinantan (equal to $2), berian ($12), sapikul besar ($22), sapikul damit ($20), salikur ($21) and dua likur ($22). Ask your great grandparents.
