The Vikings that came to Britain and Ireland are currently rather confusingly placed in categories to which they don't belong:
Anglo-Saxon Kingdoms:
Bearing in mind the Anglo-Saxons and the Vikings didn't exactly get along, this isn't right. It would be like including France in ‘United Kingdom’ because England once ruled a large chunk of the country, or visa versa.
Anglo-Saxon Kingdoms includes:
Kingdom of East Anglia:
Includes both Anglo-Saxon and Viking rulers. It is, however, an Anglo-Saxon Kingdom. The Kingdom was taken over by the Vikings in 869 (after Eadmund) and so all the coins from that point are Viking and sitting under a defunct Anglo-Saxon kingdom (Aethelstan II and the imitations). This became part of the Danelaw. In Spink, these are called ‘Danish East Anglia’ .
Vikings of York:
These are correctly titled and grouped, except they are also under ‘Anglo-Saxon Kingdoms’, which they were not. They were also part of the Danelaw.
Hiberno-Norse Kingdoms:
Hiberno-Norse Kingdom of Dublin:
These seem to be listed under rulers as part of Ireland, which is a modern state. There's Sigtrygg II Silkbeard Olafsson and anonymous types. If this made sense, then the above Vikings in England should come under the United Kingdom, not ‘Anglo-Saxon Kingdoms’.
Hiberno-Norse Vikings of York:
Note that Olaf Guthfrithson, a Hiberno-Norse ruler of Dublin, also ruled York from 939-944, and struck the famous raven pennies. His coins (and those of several other rulers of Dublin and York) are under ‘Vikings of York’ as ‘Hiberno-Norse Vikings of York’.
In Spink, ‘Danish East Anglia’, ‘Kingdom of East Anglia’, ‘Southern Danelaw’ (the imitations) and ‘Hiberno-Norse Vikings of York’ come under ‘Anglo-Viking Coinages'. Together with the Irish Vikings, they could become the Viking Kingdoms of the British Isles and be referenced in UK and Ireland searches.
