1 Penning - Harthacnut Serpent

Harthacnut ruled Denmark and England simultaneously — or tried to — spending much of his reign in England after 1040 and leaving Danish administration to regents. Coinage struck in his name during this period reflects Anglo-Danish monetary influence directly: the serpent type borrows die-cutting conventions from English moneyers active under his father Cnut, whose mint organization Harthacnut inherited without meaningfully reforming.

Hauberg's classification remains the primary reference for this type, as no comprehensive re-cataloguing of Viking-age Danish pennings has superseded it.
