Even though Queen Anne's proclamation of 1704 brought the gold standard to the West Indies, silver pieces of eight (Spanish dollars and later Mexican dollars) continued to form a major portion of the circulating currency right into the latter half of the nineteenth century. Britain adopted the gold standard in 1821 and an imperial order-in-council of 1838 resulted in British sterling coinage being introduced to St. Vincent in the year 1839. However, despite the circulation of British coins in St. Vincent, the silver pieces of eight continued to circulate alongside them and the private sector continued to use dollar accounts for reckoning. The international silver crisis of 1873 signalled the end of the silver dollar era in the West Indies and silver dollars were demonetized in St. Vincent in 1879 for fear that the silver standard might return. Even though the British sterling coins were made of silver, they were fractional coins of the British gold sovereign and hence they maintained their gold value. This left a state of affairs, in which the British coinage circulated, being reckoned in dollar accounts at an automatic conversion rate of 1 dollar = 4 shillings 2 pence.
