Bought a set of UNC War nickels. How'd I do? Need help.

Here are a few pics. I know basically nothing about nickels, so I ask which dates are the most difficult to find fully struck and in high grade. What should I look for?
I believe a few have PVC residue, but several have wonderful rainbow toning. Also a few have prominent die cracks, is that typical?

As for the PVC, just do the acetone thing.
kjjust let them soak in acetome put then in a covered glass jar covered in acetone overnight and this will take care of all the pvc just rinse them twice in distilled water and you will be fine
p.s. nice coins.
