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.
