The pre-decimal system of coinage(Prior to 1st February 1971) was based on four farthings to the penny, twelve pence in the shilling and twenty shillings in the pound. A guinea was £1 and 1 shilling or 21 shillings - a very common unit of currency and payment. Paper notes were Ten shillings, One pound and Five pounds. Some sample pictures of coins are shown below:
