However, the Board of Commissioner of Currency Malaya & British Borneo remained officially until 1967. The Malaya currency unit, Ringgit (equivalent to 100 cents ) was adopted. The value of each Ringgit was set to 0.290299 grams of gold. The exchange rate for the old Malaya dollar was set to 2s 4d, On 16 January 1969, British Malaya Dollar tender was discontinued. The Malaysian currency was fully implemented. In 1967, Malaysia first issued coins consisting of 5 denominations (1 cent in copper, the rest 5, 10, 20, and 50 cents in Cupronickel).
