Die Trash Strike-Throughs on AGEs

I've been going through my stash of Burnished AGEs that I haven't even put a glass on since I bought them, grading them as I go.
Occasionally, I come across a coin with little bits of either hard white plastic or a dark solid-looking bit of "die trash", so I lightly brush the contaminant off the coin to get a better look.
In 3 or 4 instances now, when I brush the little bit off of the coin, what I get is a shiny little divot, staring up into my eyeball.
Now I know that not every blemish is a contact mark. Even so, there's no denying that the coin isn't flawless when one of these pops up.
It appears that the correct term would then be - a die trash strike-through. Is that accurate? Does anyone else see many of these?

I dunno.
I have had gold eagles with grease, cotton thread and also wire though. I consider these all just strike-through errors. I have yet to see one with all those little poc marks like the silver eagles have had the last couple of years.

Poc marks is a good descriptor. These are 2008-Ws.
I knew it would happen.
They don't seem to effect the grade on error submissions from what I have seen.I have not received a grade higher then an MS69 on a strike-through submission but I have on a rotated die. It would be nice the for sure.
These are MS-69s. No other marks whatsoever. Was hoping for a 70 or two but I think that's not gonna happen.

Much like these spots of grease and copper:
