I am not an error coin collector although if I find one while roll searching that looks odd or is one that is listed in the Red Book I keep them or at least check them to see if they are errors. That being said you I don't know much so I am asking for help with a Lincoln Cent that is clipped on the side, it is a straight clip not rounded like some I have seen pictures of and I want to know if that is possible or would it be post mint damage? How can you tell? I also have some cents from the 80's that bubbles on the obevrse that are odd looking. The bubbles are not round they are long and narrow I was wondering if this just a defect in planchent or is it cused by the die? I will try to get some pictures I just can't do it right now. Thanks Kent
The bubbles are probably just gas under the plating, so they wouldn't have any extra value (if that is what they are). Does your clipped coin look odd on the edge opposite the clip, and do the letters and/or design elements near the clip seem distorted at all, almost like they're flowing? If so, it's probably genuine. A nice, high-resolution image of both coins would be great if you can do that.
If you can post a picture of the coin, we could tell you in a heartbeat if it is a coin struck on an incomplete planchet or if the coin was tampered with and cut after the coin left the Mint. Thanks, Bill
