A generous AU53 from those pictures. They aren't very clear but there is a lot of distractions on the obverse and I can't tell about the scratch/die crack reverse.
That doesn't look like a die break, looks more like a cat hair from the photo. I'd put this at an AU55
Yeah, die cracks are not that circular like you see in the photo. Die cracks connect between the devices in a jagged way because they are cracks in the metal die. Not quite sure what it is.
Assuming that's not a scratch on the reverse and thus it's gradable. I would call this low AU...maybe even high XF on a bad day.
