The Guinea is one of the world’s most famous coins, introduced in 1663 during the reign of King Charles II, the first Carolean Age.

Originally worth one English pound or 20 shillings, the Guinea reflected the fluctuating gold price until 1717 when its value became fixed at 21 shillings, or £1.05 in today’s decimalised currency.

It went on to play a key role in the story of British history, its influence stretching far and wide during the golden age of trade, exploration and adventure, travelling the world on East India Company ships and establishing an unrivalled reputation for quality and reliability.
