Shown are the audited numbers for the Tower mint by value in pounds. During the reign reign of Charles I almost every year had an audit and key numbers for gold and silver coinage made in that period. With the Parliament takeover of the mint in 1642 audits slipped. Complicating matters, there is no confirmation of the mintmarks in use so it is not possible to have yearly numbers. The Battle of Edgehill on 23rd October 1642 occured after the king raised his standard in Nottingham on 22nd August 1642. The period following saw the highest output of the mint between 1642 and 1645. In June 1645 the king was bankrupt and Naseby effectively ended the first Civil War. After that the mint slowed down and production subsided to a very low level between April 1647 and May 1649 - £153,286.
There were only 5 periods of audited results during the Commonwealth Period and those can be seen starting 16th May 1649.
