I am not sure about a scratch. This is fascinating, playing coin detective. Blew up the image, and raised the contrast. Look how even the depth of the mark is, and how regular, and lacking in jagged edges. That is why I think it was a die state mark—strike through. Too even to be a scratch, IMO. Also, look at the “A” in America. It looks chipped at the base. Die state is worn, common to o mint coins.
It appears that there is a break in the line like it's hitting the high spots. A strike-thru should be a solid line. Once the OP is done with the GTG on all coins we could get a full size TrueView with the cert # that should show more detail.
Yeah, I'm studying the high resolution images now. Those breaks that you brought up are making me question it as well. With as large and deep as it is, I would expect to see more displaced metal. Right now, I am starting to lean towards a scratch of some sort.
I think they would have detailed it, as a scratch. Minor scratches get ignored, but a scratch this big? I think we have a die deterioration problem. Were it a scratch, I think it would certainly have gotten a details grade for a deep scratch across the entire wing. Also, look at the right upper part of the mark—it is forked. Scratches are not usually forked. Also, look at the “A” as I pointed out. It has been clipped. I still think die issues. If the die was chipped, cracked, or misaligned, it could have created mint damage like that.
