For a long period, Hong Kong's Coinage was in some confusion. No dollar coins were issued by the Hong Kong Government for nearly a century, between 1868 and 1960. For much of this time people used dollar coins from other jurisdictions, the British trade dollar minted in India, or banknotes issued by banks or by the Government. Between 1872 and 1905, smaller denomination silver coins were minted in England for Hong Kong in larger and larger quantities. Between 1906 and 1931 the only Hong Kong coin minted was the bronze one cent piece. Early in the twentieth century, the Hong Kong Government tried to tighten up the coinage in daily circulation with a series of measures between 1912 and 1913 aimed at prohibiting the import and circulation of foreign coins. But it was not until 1 August 1937, when the British trade dollar was declared to be no longer legal tender, that the coins in general circulation in Hong Kong were confined to Hong Kong coins.
