Edward I

Edward I, also known as Edward Longshanks and the Hammer of the Scots, was King of England from 1272 to 1307. The first son of Henry III, Edward was involved from an early age in the political intrigues of his father's reign, which included an outright rebellion by the English barons. In 1259, he briefly sided with a baronial reform movement, supporting the Provisions of Oxford. After reconciliation with his father, however, he remained loyal throughout the subsequent armed conflict, known as the Second Barons' War. After the Battle of Lewes, Edward was hostage to the rebellious barons, but escaped after a few months and defeated the baronial leader Simon de Montfort at the Battle of Evesham in 1265. Within two years the rebellion was extinguished and, with England pacified, Edward joined the Ninth Crusade to the Holy Land. He was on his way home in 1272 when he was informed that his father had died. Making a slow return, he reached England in 1274 and was crowned at Westminster Abbey. (Wikipedia article).

The voided long cross pennies of Henry III type, issued in the early years of Edwards reign are shown elsewhere.  Here we start with Edward's new coinage from 1279, when new denominations were introduced.  In addition to the penny, we now see the appearance of groats, halfpennies and farthings.
