Please could someone ID this "Arthur"

[Unwilling Numismatist 505]

It's only "Arthur" a coin - but I always like finding them (Even when it's been in a box for 10 years hiding)

I believe it could be John, although really I should hedge my bets and go with "a King of England" given my ability with these

Many thanks in advance!

It looks like a John. Iohan at Canterbury. That's as much as i can see. There was a few Iohans minting at Canterbury under King John. Some had a single letter after their names to break up confusion as to who was who. 

The coins of Iohan M end in CA for the mint signature so I'd say it was probably one of his. He struck class 5b2 - 5c under John.
