In 1967, the first series of coins was introduced in denominations of 1, 5, 10, 20 and 50 cents and 1 dollar. These coins depicted wildlife and other images relating to the island nation and were designed by Stuart Devlin, the same artist credited for the 1966 designs on Australia's decimal coin series. The sizes were the same as those used for the Malaysian ringgit and based directly off the old coinage of the former Malaya and British Borneo dollar. The 1-cent coin was bronze while the other denominations were copper-nickel. Later, in 1976, the 1-cent coin was changed to copper-clad steel. The production of the first series was phased out by 1985.
