Any idea of what caused this? No markings on the obverse side.   |

Thanks Norseman. I was wondering if they matched up to anything on a coin. Maybe someday I'll learn how to overlays.

Your welcome I am going to try to see if anything on the penny will leave any kind of marks on it like what you have in your pic's

Nope. No idea what caused it.

My guess is post mint damage. It looks like the marks go into the rim and flattened it down where they go into it. The rim is formed when the design is struck so that means the marks were put on the coin after striking or post mint. But I am assuming the marks are indented into the coin and not raised. Is this the case?

Hi I have no idea what is on that coin myself but I am a little confused about "The rim is formed when the design is struck" I always thought the rim was formed when it was put through the upsetter. Then the devices after that during the press. Was the LMC minted differently ? |

Indian, isn't the rim formed here because the area where the field ends and the rim starts is the edge of the die? When you see a misaligned die it has a wide rim on one side and a thin or no rim on the other side. So the rim is actually caused by the pressure of the strike. This is an interesting coin and I don't know what happened either but post mint damage is my guess because of my rim assumption here. Correct me if I'm wrong.

Hi
I would also have to agree in my opinion that this coin most likely
has post mint damage. The collar holds the planchet in position
during the strike. Some coins are struck with no collar. Normal striking will push the metal out and around some. I think I understand what you are getting at though and why. Anything may be possible but I would like to hear what others who know more would say.

I looked closer at those pics. and have changed my opinion.
I beleive those marks (not sure what caused them yet) was
done at the press. They seem too clean and with no other damage
evident in the near surrounding areas. I think if you do not look at
them as possible lettering, you can see maybe tool markings or ?
Maybe this is a test ? :) O.K. who did the garage job ?

I understand what you mean about the surrounding design. I struggled too with how this is post mint damage but it didn't damage the "A". I don't have an answer to that. But if one thing sticks out to me as post mint damage then I base the evaluation on that. The part I explained at the rim is the best explanation I can come up with. I'll have to stick with that until Mike or one of the other experts looks at this and changes my mind. It's funny how they can do that with a couple of key strokes! Also, as I said in my first post, this all changes if the marks are raised and not indented. But they appear to be indented. Nice coin LilBlue. Don't give up on it until you hear from an expert. Thanks for posting it.

Thanks for commenting on this coin. The markings are indented. Here's another pic without me blocking the background light and you can see the indent.  |

Although I still have no idea what caused the indentations on this coin, I can clear a couple of things up.
The rim of a planchet is caused by the upset mill before the planchet goes into the coining chamber on the press. The rim is further assisted by the bevels at the edges of the die, which helps form them. Coins that are struck off center flatten that rim when the coin is struck...so...
The rim is actually formed on a planchet before the strike, but can be flattened by the strike.

Thanks for clearing that up Chuck. Then that means I am wrong with my guess that this could only be post mint damage at the rim. I really do appreciate you pointing out the details that I miss. When I answer posts I give details so that when I am wrong I know why and I learn from my reply. Learning when I am wrong is more important to me then being right. All the experts on this site make it a great learning tool and you are certainly one of the experts. Thanks.
So now this has been posted for several days and LilBlue still doesn't have an answer. Can anyone contact Mike or have any ideas what LilBlue can do next. Of course one option is to send the coin to one of the major grading services.
