I have attached pictures of some penny’s that I am trying to determine if there is any value to. 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.
The 34 with the S missing is probably from grease in the die. I'm not sure about all the other stuff.
The first one looks like it was subjected to some form of acid treatment. Though the lines on the second coin may seem raised to you, they appear to be deep gouges running continuously over one another. The coin metal is pushed up over some of the gouges. The third coin looks like it is the result of a grease-filled die. These are very common and can be found in practically every denomination. They are usually only worth what someone is willing to pay for them, but I wouldn't pay more than face value because they are too easily found in circulation.
