The gold guinea was, for almost 150 years, the standard gold coin of the British currency.Originally, it was valued at £1 (twenty shillings). It became known as the Guinea because it was first minted from gold brought to England from the Guinea Coast of Africa. Hence, it was called the Guinea-Pound.
From the 1717, its value rose to twenty-one shillings due to an increase in the value of gold in each coin.
The Guinea was minted between 1663 and 1799 (although a military commemorative issue was made in 1813). From 1817 onwards the Sovereign took its place as the premier British gold coin.

By the year 1812 the gold in a guinea was worth 27 shillings (6 shillings above its face value) and it became widely hoarded.
In Victorian times it was a fashion to use a gold guinea of George III as a fob on a key chain
