The dollar was the currency of Sarawak from 1858 to 1953. It was subdivided into 100 cents. The dollar remained at par with the Straits dollar and its successor the Malayan dollar, the currency of Malaya and Singapore, from its introduction until both currencies were replaced by the Malaya and British Borneo dollar in 1953. During the Japanese occupation period, paper money was issued in denominations ranging from 1 cent to 1,000 dollars. This currency was fixed at 1 dollar = 1 Japanese yen, compared to a 1:2 pre-war rate. Following the war, the Japanese occupation currency was declared worthless and the previous issues of the Sarawakian dollar regained their value relative to sterling.

The 5 and 10 cent coins were 80% silver until 1920, when they were briefly reduced to 40% silver and then replaced by copper-nickel the same year. The 20 and 50 cent coins remained silver but in 1920 were reduced from 80% to 40%.
