Cut or Clip in 2005 kennedy half dollar, uncirc mint set
Hi, This is my second thread to this forum. Got some great advice on the first one. When I received this 2005 uncirc mint set, the kennedy half dollar had a cut in it. It is in the mint packaging, pic attached. Is this considered a clip?

directed toward the reverse. A little of the clad layer was torn off with it implyimg a weak
area in the cladding. While this apparently occured after the strike I'm also guessing
that the planchet was oriented like the coin when it was cut from the strip, i.e. the copper
which shows on the edge is toward the reverse.
There should be a discernable difference in height between the copper area and the adjacent
cladded area if this is post strike damage.
What doe the opposite rim on the reverse look like?

Another question: it looks like the copper color extends out from the nick on the rim onto the solid rim adjacent and even into the field above the B. Is that copper color really there on the coin, and if so does it look like the copper is sitting above the clad, even with the clad, or under the clad? In other words, was the cladding removed after the strike, was it misssing before the strike, or was come of the copper core struck or moved down onto the clad layer?

I really doubt that is a clip but we need to see the opposite side of it, as in.. straight across from the 'clip' not the otherside
However like I said.. I doubt it's a clip
<<Thought I would share this little tidbit of education with the folks here, especially considering the number of new people we have that may or may not have heard of this little factoid of numismatic information.
I was going through some pocket change this evening and ran across a single wheat cent out of thousands of memorials, and that single wheat cent happened to be an interesting little error...it was a clip, and not just a clip, but a straight clip, which is a bit less common than it's curved clip brother. You see, a curved clip can happen anywhere in the sheet - simply by having two rows of blank punches too close to one another you end up with a full row of incomplete blanks when the second of the two rows is punched. A straight clip only happens when the sheet moves too far left or right and the blank is cut off the edge of the sheet.
Anyhow, this particluar little straight clip shows an effect that isn't always present on clipped planchets, but when it is you can just about guarantee its authenticity by it. If you look at the design just opposite the clip (in this case the letters of TRUST) you will see that the design and rim is a bit weak up there. This happens because the rim is rolled up, or "upset" in a mill that rolls the blank around and makes it round and raises the rim for better striking. It works by rolling the planchet around a wheel that has a groove in a trench that the blank won't fit through without crimping it. If you think of a blank being round, it would raise the rim all the way around...but if there were a piece missing, the area opposite the missing piece wouldn't receive the pressure necessary to raise the rim...sort of like an out of round shopping cart wheel with a flat spot....bump, bump, bump as you shop, embarassing you all the way. We've all had that happen and wish we had picked a different cart. Well, in coin making, the Blakesley effect, so coined from the first person to realize and describe the cause of the effect, is the result of a blank being upset that started through the machine out of round...with a clip.
Enjoy, and ask questions...that's the only way you'll learn. Unless people like me hang around way past their bed time writing blather about what interests them.>>

Would this be something to submit for grading, or to hang onto, or just put away as a problem coin.
No Blakesley effect 180 degrees opposite the spot.

<< <i>I'm pretty confident that this is pre-strike damage. It's probably a close relative of a rim burr, although in this case a "fang" wasn't torn up and struck into the coin. The fact that the copper core is exposed on the rim and is flush with the surrounding surface is consistent with damage before the strike. >>
I agree.
I also have to say something about people thinking it might be packaging damage. The "jaws" that seal the mint sets do not carry enough pressure to "chop" metal.

You're no doubt correct about this but I've seen mint set coins with extreme post-mint damage.
Frequently this damage is from some sort of shearing force and will look as though the coin was
damaged by a large pair of scissors. The coin will actually be cut and distorted by the force. I'd
guess these get caught up in the machinery somewhere, perhaps in the drying process.
