What is the weight of this coin?
If it is a clip, it should be slightly under 3.1 grams.
If it were a clip, the details would be clearer in the area of the clip "LIBERTY". The coin looks like it has a formed rim in that area also, extending into the field, like it was pushed there.
I'm not saying it's not a clip, yet. I want more information.

EDIT: If you look closely at the area suspected of showing the Blakesley effect, it looks like it has flattened out the metal like it was smashed there, making the coin out of round. It's difficult to tell for sure from these images, but worth checking out.

Another good indicator if genuine is a weak strike of the devices and design close to the clip. I definitely see a weakness in LIB of liberty & part of the wheat stalks on the reverse which indicates the clip was present before the planchet was struck. Along with the other indicators I believe it to be genuine. IMHO

As biokemist6 said it's

It is a ragged clip, the blank was most likely punched from the edge of the metal stock sheet.

It must be a clip.
The part that has had me wondering is the area around LIBERTY. It looks like a formed rim there and something just doesn't look right.
Interesting find!

A ragged clip happens when the punch out of the blank fall over the edge of the metal. The original metal roughness will be seen on this area. This one is pretty straight. But sometimes they don't look that way.
Sometimes split:

I'm still not saying that it isn't a clip, but none of the examples you show have a formed rim in the area of the clip like the original poster's does.

Actually the photo of the 2003 shows the exact same edge opposite the clip if you look closely...beveled edges where it filled in, etc...

I don't mean the edge opposite of the clip, I mean where the clip is.
I even think it is a clip, I just don't understand why it appears to have a formed rim in that area.

cwb, I see it too. More so on the reverse. Lack of material distorted things a bit. Not to mention its magnified. All in all it is a ragged or straight clip.

Wanted to follow up on Blakesley effect. Some may make it read like its the result from the strike because of a clipped planchet. When in fact it is already present prior to strike as it is created during the upset process, because of a deformity in the blank being processed through the upset mill into a planchet. This creates a weak proto rim opposite the clip or anomaly prior to strike.

I maybe wrong but read it something like that years ago. Thanks, Doug.

You're not wrong, that is how it happens.
