1976 Bicentennial Half Dollar Double Clip, Man Made or Mint Error?

I started CRH half dollars back in 2013, for over 8 years and I came across this half dollar that appeas to be a double clip. I haven's seen a hole lot of these clipped coins to tell for sure if someone outside the mint did this or it happened at the Mint. I don't see any blaksley effect on this coin, which doesn't mean its not a true error. I also don't think a clip top to bottom clip can happen during process. Also the edges of the coin at the clip a very rough, I believe they should be much smoother? I believe this is fake, what do you all think.

I've also done the CRH for about a dozen years back in the early '00s and never found a clipped Kennedy. The absence of the Blakesly effect would be due to the opposite side of the coin being clipped as well; however, I'm inclined to believe that this example is PMD due to your excellent pics of the marks on the "clips".
PMD
I will say Post Mint Damage.
As you said, the clipped edges are too raggedy.

Kennedys are my quest...
Definitely man-made
No metal flow on the letters near the fake clips so they are fake clips.
Error Ref Has a good section on the characteristics of clips (incomplete planchets) including the "punch and tear" edge appearance. There is also an embedded link which gives more detail.
