I hate it when my gaydar goes off so forgive me for airing my concerns. It has all the look of a fake. From its metal looking appearance along with so many things that are wrong about the coin including Fred Flinstone's Dino try to pass off as the Scottish emblem in the shield. I don't know what is in the centre and the quartered surround doesn't look quartered. Coins and designs are made in a symmetrical nature and it just looks like everything is out of proportion.
It could be just a bad angle from the camera but I very much doubt it If it's genuine I am Elvis. The conmen in this field are a blithe to the coin collecting fraternity and the sad thing is they are getting better. This probably answers your OP why does the shield have 2 lines and not 1 .
