1940 S Lincoln Wheat Cent - Dent In Date For Discussion

I've seen a bunch, but if I remember correctly 1940-P has a lot of coins that look like this as well. Don't remember any D coins but it all blends together after a while.

Very nice coin!

I'm just going off of lighting here which can be misleading. In the first set of pics I have circled north and south points. The north point looks to have a rounded entrance into the anomaly while the south point looks to have a sharper ridge. The lighting is coming from 3:00 o'clock so this might explain away what might be a preasure ridge.
The second set of pics highlights a area of shadow across the 0 that could be the result of the lighting at 7:00 o'clock and a preasure ridge.
TB
Do you note any evidence of a preasure ridge or is this just a lighting anomaly that I see.
Side note:
I doubt this could be from something like a Coin Wrapping Machine as there are no linear lines through the anomaly

Yes, I don't know if it is a pressure ridge, but as I noted in the description the metal is raised to the east of the dented area, slightly rising above the level of the rest of the 0. I certainly offer it as possibly of PMD, yet this just doesn't seem like PMD. Maybe there is some poorly understood feeder finger issue or some such thing that hits coins just so post strike, but this is so flat against the field and below the rim that it's hard to imagine machinery getting in there, and consistently at the same angle and on the same place on the coin.
