It’s called a magician’s coin and was made from 2 coins after they left the mint. You can see the seam on the one side where the coins are joined. Not a particularly good example because the seam is obvious. These are considered damaged and really don’t have any collector value, although somebody may have an interest as a novelty BTW: It looks like both coins are a Geo V British Penny. These were minted between 1911 and 1936
