This is the history of the English penny from the years 1154 to 1485.
King Henry II ascended the throne in 1154 as the first of the Plantagenet dynasty. For the first few years of his reign the coins of King Stephen continued to be produced, but in order to restore public confidence in the currency a new standard was introduced, known as the Tealby penny after a hoard of such coins which was found at Tealby, Lincolnshire in 1807. A total of 30 mints were employed in the initial recoinage (the mint at Ipswich was not active during the early stages – but was extremely productive from class B until the end of the series). The mints in operation at the beginning of the recoinage were:Bedford, Bristol, Bury St Edmunds, Canterbury, Carlisle, Chester, Colchester, Durham, Exeter, Gloucester, Hereford, Ilchester, Launceston, Leicester, Lincoln, London, Newcastle, Northampton, Norwich, Oxford, Pembroke, Salisbury, Shrewsbury, Stafford, Thetford, Wallingford, Wilton, Winchester, and York. However, once the recoinage was completed only 12 mints were allowed to remain active. This marks the beginning of the gradual decline in the number of mints used to strike English coins.
