hello i found this coin in liverpool when i was a kid, i have no idea what this is, looks like it could be bronze, is it saxon, norman or arabic i have wondered, it is about the size of a 50p coin its cut is pretty neat which baffeled me further, i cant see a date its pretty worn but from what i can make out it has a strange text running around the coin similar to arabic but much more squared in shape, looks like it has a small head wilt a helmet or somthing, the other side of the coin has a wavey line running around the outer of the face and again the strange text but this time in the centre of the coin, i can put more pics on if you need, it was found at a fields edge which was undisturbed for some time, any help would be great thanks
