File:Early medieval coin, Viking penny (FindID 943967).jpg

English: An incomplete silver early medieval penny of the Vikings possibly minted in the name of Sihtric (c. 921-927), imitating coins issued in the name of St Peter, Phase 1 or 2, Two-Line (Horizontal), (North 551 or 553), minted in York, c.905-920. Diameter 18.4mm, Thickness 0.6mm. Weight 0.93g,

The coin is influenced by the Swordless St Peter type, which are inscribed with SCI PETRIMO (cf North 551) or a blundered form of this. Megan Gooch says these letters "get more random as shapes such as the key find a home in the field and take up design space". pers. comm 8/4/2019.

However, Gareth Williams says the inscription is closer to Sihtric than St Peter, but "in the case of imitative die-cutting which is not entirely literate, it does not have to be either/or, but could draw from both". Many coins of this period appear to have inscriptions derived from Edward the Elder as well as St Peter and it is possible that this example was influenced by coins of Sihtric and St Peter. This would not fit well with established chronology of these coin types - Sihtric's coinage are currently thought to begin after swordless types stop being minted - although it is not possible to assign hard exact dates to the types anyway. Unfortunately, the coin is incomplete and is missing a letter or letters that might give more of an indication of its origins. Gareth Williams pers comm 8/4/2019.
