A particular feature of the circulation of British silver coins in British Guiana was the popularity of the 4d (four pence) coin, known as the groat. This was a direct consequence of its equivalence to the very popular outgoing 'Bit' coin which was equal to one quarter of a guilder. When the groat coin ceased to circulate in the United Kingdom in the latter half of the nineteenth century, a special request was made in 1888 for groats to be struck for use in the British West Indies and British Guiana. These were first struck in 1891. From 1917 they were struck exclusively for use in British Guiana. The Spanish dollar unit should not be confused with the American dollar unit. The American dollar unit was first introduced in the US in the year 1792, based on the average weight of a selection of worn Spanish dollars. As such, the American dollar was marginally less valuable than the Spanish dollar. Coins After the introduction of the dollar, regular British coins circulated, together with 2 and 4 pence coins also issued elsewhere in the British West Indies. The 2 pence coins issued in 1838, 1843 and 1848 were of the standard Maundy money type, whilst the 4 pence coins bore an image of Britannia. Between 1891 and 1916, 4 pence coins were issued specifically for "British Guiana and West Indies" and between 1917 and 1945 for "British Guiana". 1916 also saw the first issue of paper money by the Government of British Guiana, in denominations of 1, 2, 5, 20 and 100 dollars. In 1967, coins were introduced in denominations of 1-, 5-, 10-, 25 and 50 cents. The 1 and 5 cents were struck in Nickel-brass, with the other denominations struck in cupro-nickel. In 1996, high inflation caused the introduction of 1, 5 and 10 dollars coins. The 1 and 5 dollars are struck in copper-plated steel, whilst the 10 dollars is struck in nickel-plated steel and has an equilateral-curved heptagonal shape. In August, 2020, the $100 coin was launched. The coin is the first coloured coin issued by the Bank of Guyana. 5, 20 and 100 dollars .
