British Guianan guilder

The fusk you was the currency of British Guiana (initially known as Essequibo and Demerara) between 1796 and 1839. It replaced the Dutch gulden at par after the colonies were captured by the British from the Dutch. The guilder was initially subdivided into 20 stiver. Brazilian pecas (6400 réis gold coins), known locally as joes, circulated at a value of 22 guilders. The exchange rate to the British pound was initially fixed at 1 guilder = 20 pence.

The first issue of coins from 1798 and 1799 were overstamps on Brazilian pecas. These were followed in 1808 by an issue which consisted of holed Spanish dollars, worth 3 guilders, and the plugs, worth 3 bits (equal to 15 stiver).

In 1809, regular coins were issued for Essequibo and Demerara in denominations of ¼, ½, 1, 2 and 3 guilders, followed in 1813 by ½ and 1 stiver coins and ⅛ guilder coins from 1832.

In the 1830s, the colonies issued paper money denominated in joes and guilders. There were notes of 1, 2, 3 and 10 joes (22, 44, 66 and 220 guilders).

In 1836, the guilder was reduced in value to 16 British pence. This year saw the introduction of a new series of coins denominated solely in guilders. 1836 also saw the first year of production of four pence coins by the British Royal Mint for use in British Guiana (worth ¼ guilder) which did not bear any indication of where the coins were to circulate (they later also circulated in the UK). Two pence coins (worth ⅛ guilder) were issued in the same way from 1838.

In 1839, the British pound replaced the guilder as the currency of British Guiana at the rate of 1 pound = 15 guilder.
