Check out this CNUT penny, with moneyer Efin from York. I’m not sure how to reference these, I used North for a Mercian coin. How would you guys do that? I would also love to see your Saxon England coins ! 17mm 1.18g
The standard reference for English hammered coinage is North vols. I and II. However, there are some more specialist references when it comes to specific mints or monarchs. Later Anglo-Saxon pennies like these are frequently referenced with the standard SCBI volumes - particularly those referring to The Hermitage Museum St Petersburg and Royal Coin Cabinet of Stockholm/Hildebrand.
