1962 D LMC What Happened To Liberty?

I lean toward damage.

Looks like an attached fold over lam over the edge of the coin. That is what I'm seeing.

Thanks all, here are my deductions:

1. Liberty was stamped then some lamination peel took place, suggesting it occurred after stamping but before ejecting out of the (insert name here please of device that holds planchet for stamping...the collar?).
2. The rim has one end folding over the other... what is this called and why does it happen?
3. There was a planchet defect as shown by the crack on the rim. What is a planchet defect and are there different types besides this crack?
4. My assumption: there was an air bubble or some gas in the metal...can this happen if the alloy mixture is contaminated.
5. My conclusion/guess: After the planchet was stamped by the dies, an air bubble burst out of the planchet and the coin move slightly right before ejection and some machinery scraped metal off the coin, creating the crack and peel in immediate succession.
6. If there is a process after the coin is ejected, is that when the fold is created, if so, what machine?

Puzzles that help you learn are the best, ideally someone can explain the error of my logic.
