tough call with that much glare from the lighting which is resulting in shadowing. its hard to say if there is any circulation wear due to this. I think what you have are bag hits and die polishing lines combined. the issue is determining what caused some of those hairlines across some of the devices (bag marks or a cleaning)
i can only come up with 4 possible grades better photos with less glare would help narrow it down.
1. AU55 net straight.
2. AU details
3. UNC details
4. MS62 straight
i think there are too many hairlines and hits to pull a 58 straight
