Brunei dollar

Due to the close ties between China and Brunei, the first type of coins used in Brunei were Chinese coins. This was initially called ‘Pitis’. They were later known as ‘Kue’ when local ‘Pitis’ were introduced.[2][3] The local ‘Pitis’ coins had ‘Sultanate of Brunei’ stamped in front of the coin and the royal umbrella was imprinted at the back. These were issued from the 16th to the 19th century. Previous Islamic coins were also called the ‘Pitis’.[4] Another type of coin that was used in Brunei were ‘Duit besi’ (which roughly translates to ‘Iron money’). Iron was considered valuable those days that it was used as money. 100 one-square inch pieces were valued at 1 dollar.[3]

The last coin to be issued before the introduction of the Straits Settlements currency was the ‘Duit Bintang’, otherwise known as the ‘Star coin’ or the 'Star Cent'.[2] It is called the Star coin because of the star imprinted on the obverse of the coin. It was minted in Birmingham, England, in 1887.[2] It was made from copper.

With the introduction of the Straits Settlements currency, the previously used coins were taken out of circulation. They were, however still used with certain exchange rates.[3]

One Straits dollar banknote from 1935

The Straits dollar was introduced in Brunei in 1906. It was later replaced by the Malayan dollar which was introduced to British colonies and Brunei in 1939. It replaced the Straits dollar at par with a 1:1 exchange rate. The Malayan dollar was issued by the Board of Commissioners of Currency in Malaya. The board stopped issuing the Malayan dollar during the Japanese invasion during World War II. The Malayan dollar had the portrait of King George VI in front of the note.[2]

In 1952, the board was renamed the Board of Commissioners of Malaya and British Borneo. The board then began to issue notes to Malaya, Singapore, Sarawak, British North Borneo, and Brunei in 1953. This was known as the Malaya and British Borneo dollar.[2] In 1967, the Malaya and British Borneo dollar was replaced by three new currencies: the Malaysian dollar, Singapore dollar and the Brunei dollar, all at par.[5]

The Singapore dollar is still interchangeable with the Brunei dollar today.[4]

The S$10,000 and B$10,000 notes are the world's most valuable banknotes, worth USD 8000 as of September 2014 (that are officially in circulation).[9] They are worth eight times as much as the next most valuable, the 1000 Swiss franc note (USD 1063). From 6 November 2020, AMBD has announced it will stop printing B$10,000 notes to reduce the risk of money laundering. Brunei has also stopped the issuance of B$10,000 and is in the process of withdrawing it from active circulation.[10]

• $1 – blue (2011)[11]
• $5 – green and yellow (2011)[12]

To commemorate the 65th birthday of Sultan Hassanal Bolkiah.[14] Shortly after the notes were issued, the Braille dots on the upper left front corner of the new polymer notes are not raised. The Braille dots cannot be felt tactilely, and they are not accurately rendered as Braille numbers corresponding to the denominations. Specifically, the spacing of the dots is wrong, and they lack the lead-in character that indicates that numbers follow.[15][16]

On 27 June 2007, Singapore and Brunei celebrated the 40th anniversary of the Currency Interchangeability Agreement (since 12 June 1967) by joint-issuing commemorative $20 notes.[17]

The two authorities issue distinct versions of the new $20 notes. They are both yellow, 149 × 72 mm in size, and made of polymer. The reverses are almost identical except that the Brunei version has their state title in Jawi script, while the Singaporean version has the state title of Brunei in Latin script.[18] The obverse of the Singaporean version is similar to the current Portrait Series, whereas the obverse of the Brunei version is similar to the $50 and $100 of the 2004 series.

There is a limited edition set, which consists of both versions in a folder, with matching serial number. The notes have "40th Anniversary Currency Interchangeability Agreement" overprinted on obverse. In addition, the Singaporean version has the two countries' state crests above the commemorative text. Only 12,000 sets are available, 10,000 from the Monetary Authority of Singapore, and 2,000 from the Brunei Currency and Monetary Board.[18]

The circulation version has been available since 16 July 2007.[19]
