Hello everyone this 2015 Nebraska quarter has some anomaly on both sides of the roof. Not sure what it is or if it has a value. It isn't a raised type, but instead is sunken in a little. I could see one hit doing this, but two hits and right on top of the roof seems strange. Looking for some thoughts or insights. Thanks everyone!
Since you say that it is sunken (recessed), it is probably the precursor to a full-fledged die break. Some die breaks begin as a sub-surface crack, and as they increase in size, the surface of the die rises so that the recess you see on your coin becomes visible. Below is a die crack that began just this way. Unfortunately, I no longer have the images of the recess.
