I know there is some discussion whether the obverse should be rotated 180 degrees, and thus should represent a wolf or a porcupine, but that's another story (and I like to think about it as a boat ) HR Mossop was apparently a proficient collector of Celtic and Anglo-Saxon coins. A large part of his collection was sold in 1991 in an auction by Glendinging's London. I bought the coin from @AnYangMan, who bought it from HA-Europe in 2018, as part of a group lot. It would be nice if I could check whether this coin was indeed part of the Mossop collection, however I've used all my online sources without any result. So any help would be greatly appreciated!
