Here we have four Ploughman tenners, all graded in the VF region, by the same company in and around the same time.
Are the two '20' notes the same grade, and are the two '25' notes the same grade? Why not use numerals between 20 and 25 for more accuracy?

I would grade this one as VG

This one as Fine grade

This one I wold grade as Vg to About Fine

This one I would put at Good Fine
