These were not issued because the Japanese sank a ship carrying 1-cent coins bound for Hong Kong in the Second World War. The following year (1935), cupro-nickel 5 and 10 cents were introduced, replaced by nickel in 1937 and nickel-brass between 1948 and 1949. Copper-nickel 50 cents were issued in 1951 and first bore the name "fifty cents" in both Chinese and English, but these were changed to nickel-brass in 1977.
