1959 Roosevelt dime metal on the back of his neck

image_48978.jpg Good evening, this Roosevelt dime does not fit the label as doubled, die gouged nor cud so I don’t know what to call it. what is this type of error called?

In my opinion, it could be a sliver of extra metal. Almost like a localized strike through.

It could be a re-tooling of the area by a mint employee, to clear out some buildup/debris within the area.

It could be that the area has flaked away due to age of the die. Not a true die crack, but more of an area that has significant wear in one area on the coin.

It might be considered minor, since the magnification appears to be higher than 10x.

Thanks, Gary, I didn’t realize I should pay attention to the magnification. I will recheck and post another picture. Great information I appreciate it. I appreciate your help identifying.
