Old English hammered coin

I can see a bust of some sort facing the left relative to me looking at the coin , I can't make out the other side at all, it has a proper pie shape rim for both sides due to how it's hammered or pressed. It's about the thickness of a £1 coin, any help in the right direction is appreciated, I have a load of randoms to get through so watch out for my posts :)

​ What - nothing like it ??!

Hi, I've clicked on the link you recommended, but it's just took me to a coin page referencing ½ Mark - Wilhelm II type 2 which makes no sense as it's nothing in relation to the coin I've put  ? But nonetheless I appreciate your advice :)

wow Déjà vous!
