1 mil, km#1, VR of course for Queen Victoria, value about $2-3 in VG, $100 or so uncirculated. I would call this VF details/net VG because of the corrosion; it may have too much surface metal eaten away for any conservation methods to restore it. For me, the coin would be added to my collection as is, stored in a way to minimize and slow future corrosion. Final grade: ILIAL (I like it a lot).
