Appears it could be a die break, but pretty unusual for an edge to edge break. @paddyman98 would you like to reevaluate this nickel?
@NubFu69, in case I didn't already post this for you, here it is again. For the best results, you should post "in focus," FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and are easily enlarged by clicking on it). Photograph coins on neutral backgrounds like black, grey, or white. Crop out superfluous background so just the coin shows (you can use https://www.remove.bg for free), and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck.
I would agree with it being a die break. Given the shadowing just before the anomaly reaches the roof, it might even be vertically displaced. However, as you subsequently noted, without significantly better photos it becomes purely an exercise in guessing. Semper Fidelis
They say some things are just best left alone. However, I can be pretty slow on the uptake at times sooooo, I'm wondering if I'm missing something here? Semper Fidelis
Sry unfortunately I lack many skills and photography tends to be one. My self shots I try to keep offline lmao. See if this is any better. Be patient. As my female says... I'm a work n progress
Much better Photos; it looks like the "work in progress" is doing a good of progressing! And I will repeat, as I and another previously posted, it looks like you've found yourself a nice example of a coin struck with a cracked die; a keeper for sure and nice catch. Semper Fidelis
