1979-P LMC Hoping This Is Another Die Clash

Thank you for the link to the overlays; that is awesome.

I don't know what else has that appearance but when I first looked at it I thought about the portion of the Memorial on the reverse on the edge I refer to as "razorback" because the points look like it. (see small photo).

Could it be a floating die clash?

Dude, what it appears you have are Die gouges. Here's a diagram of what a die would look like from the side. Remember it is reversed image. If a scratch happened across the face of the die from one of many mechanical motion parts of the press it could go in between the devices or across the whole device like this on the B. Good eye to catch that!'




Pardon, the B is an E, but the principle is the same.
