The first one is a 196? Penny with the rim of the penny completely missing. The second one is a 1946 Wheat Penny with what looks like at first glance a circular scratch on the reverse side of the coin but using a magnifying glass you can see that the scratches are not scratches at all because they are raised above the wheat and the letters. The third one is a 1934 Wheat Penny with the S on States missing. It looks like part or all of it was there at one time but I am not sure.
