1923 Peace - Feather Earring Variety?

If it's incuse, it was not on the die, but something in between the die and the coin. Which would be a strike through error, like I said.

TC is right - being incuse strongly indicates a strikethrough. I've just never seen one like this before, and it is very neat-looking. As you can see from the first image posted, there isn't a lot of wear on this coin. Not saying it ISN'T a lamination error, but it just doesn't appear to me to be one. Woodchips are an interesting possibility, but wouldn't they get crushed and splinter under the force of the die?

Here are a couple of macro photos that better highlight the error. Both have been strongly contrasted to further highlight the error. The first one also had an LED flashlight shining on it from the left - unfortunately, it also illuminated imperfections in the flip's mylar.

Huh? Do you know of more coins with the same error as this coin?

I thought they were different coins. I see it now. I am sorry for being dumb.

Looks like you found a nice struck through debris. Very nice! I do not see it as a lamination.

Well, seeing as how I was unfamiliar with woodchips being part of the die polishing process, I think we've figured it out. And I learned something in the process - thanks, all!

While not a Peace dollar, these embedded wood chips are in a 1904-O Morgan dollar. They do show up occasionally on coins. My guess is your Peace dollar feature is a strike-thru from a wood chip also.

I don't want to highjack the original thread. My only point in showing the coin was to educate those who may have not seen a "wood chip" dollar to show that the phenomenon is real, and not just a theory. Now, to the subject Peace dollar, I say it is a result of a strike-thru, and a wood chip could be the culprit, but it could be something else of course.
