The one-cent coin, introduced in 1863, was the smallest-denomination coin of the Hong Kong dollar from 1866 to 1941. Coins were minted irregularly. The last issue was mostly lost because of World War II. It had two different sizes, the larger one was replaced in 1931.
The initial coin was 17 mm in diammeter, 1.8 mm thick and weighed 7.53 grams. The obverse featured the reigning British monarch: it was introduced under Queen Victoria and later featured Edward VII and George V. Like the smaller version issued beginning 1932, it was made of bronze. The smaller version started under George V, the final issue in 1941 was the only one to feature George VI. The royal titles were written in the English language, as opposed to the Latin written on British coins. While the monarchs wore crowns on the coins, it was not until the decimalisation of the British pound in 1971 that they would wear crowns on British coins.
