There are three substantive types of English coins during the reign of Cnut. Each does have regional variations and we see that coins will differ from the same mint and moneyer, and there is considerable fluctuation in the sizes and weights of Cnut's coins. The three main types of pennies were issued during his lifetime were : the Quatrefoil type (c.1017-23) with a crowned bust facing left, with a sub-type featuring a diademed bust facing left; the Pointed Helmet type (1024-30), and the Short Cross type (c.1029-35/36) showing the King with a sceptre, again with a sub-type replacing the sceptre with a banner, lance or crozier. A fourth and rare type in Cnut's name, with a Jewelled Cross, is considered to have been issued by his widow after his death to promote the succession rights of their son Harthacnut.
