finning on this cent?

[kurtrr]

This structure on a '45-S wheat cent appears below "liberty." It looks shelf like and appears to be not connected to the field. Debris under the shelf makes it hard to be certain. On the rim side it appears to be an arc of the same radius as the rim. The lower part of the "fin" seems to be attached to the rim but on the field side not the edge side.
I don't see any evidence of finning elsewhere along the edge or rim. The "fin" looks like copper. At least it has that color.
The pictures show the area with light from the left in one pic and from the right in the other.
What I'm thinking is this is a "Fold over Fin."

In my opinion, it could very well be a fragment.
The finning, the way I remember it, was associated with the rim but on the outer side of the coin.
I will see if error-ref.com has a technical definition and photos.

Here is Error-Ref's definition:

Thanks for the ref. I'll have that site bookmarked but haven't checked it out enough. I'll check that the next time. I've only recently got the difference between variety vs. mint error clear in my mind.

What I'm thinking is this could have been produced by die tilt because it is confined to a small area. The vertical fin could have been folded into the field in wrapping or circulation. Also parts of the fin could have been broken off.
Contrary indications are that between the edge and the rim it is not particularly knife-like/sharp. This could have been rounded by circulation. I'd say the coin is in VF-30 condition.
Any other considerations?

I could send it in. I am confused by what is attribution vs. examination. I want to send it to the right people.

[MintErrors]

Attribution is for varieties like Doubled dies, Re-punched mint marks, Over mint marks, Over dates, Misplaced dates, etc.
Examinations is for errors.

So its best to post this in the CONECA SERVICES forum.
See if they are willing to take a closer look at it.
Post under the Examinations forum. I have never had to use the service myself, but many do.
Add as much text and photos as you can. This way, you might get the answer your looking for in one pass.

For future reference, the CONECA staff frown on talking grades on raw coins.
They don't mind if the coin itself is encapsulated by a third party grading service.

Thanks again! I'll check out the examination service. I'll also be more general about the amount of wear of a coin and not so specific and give a as to it's grade.

Finning on the Cents?
Consider this! Extra Metal
In the past, before the mint purchased their blanks, there was a machine called the “Blanking Press Gang Punch”, in which a punch is driven thru the thimble and out comes a blank. Punching metal crates heats, heat melts metal, hot metal sticks to blank, blank is washed, upset (metal is laid down), struck, bagged, released into circulation and years later we are talking about it. I don’t believe it is finning because the metal is on the wrong side of the rim. Since finning is forced metal extruded by over pressure between the rim and die. Dave
