1968-D LMC: Crooked Things? Help In ID What And Cause?

It all falls into a straight line. I would say PSD. Something moved across the coin damaging it. If it were a die anomoly, a lot of other coins would show this.

Most of the time the beatings coins take are called bag marks. These are from coins in a bag/bin the was dropped on each other after they are struck. Coin wrapping machines disturb the outside devices and the distortion is parallel to the rim. Coin counters/coin vending machines/casinos put wear on the outside devices and rims. But when something blunt hits the coin, it can disturb the devices depending on what it was.direction/force behind the object causing the damage. What ever happened to Pete's coin, I don't know. But it wasn't struck that way. The devices were moved somehow.

I may have found some support for this idea...I have looked again at the coin, turning it at various angles in the light. There appears to be a slight concave area covering maybe a little over 1/3 of the upper half of the reverse. The features in question would be on the left hand side of this concave area. It is too mild for it to show up in a photograph and there are no additional marks of any kind visible. It seems like a strong hit would not cause this, but I can imagine an object pressing on the coin with increasing pressure. Seems to me that kind of scenario could have this kind of effect without causing any additional marks. My imagination stops at that point, however, because I cannot see what circumstance there might be for that to happen.

Then again...maybe it is an optical illusion?

Interesting (to me) anyway.

Thanks for looking and thanks for the help.
