None of those are Kev ,sorry i have not got a good clear picture that would help to show you properly ,plenty of them in low grade though.
If you were checking a BU one it would be much easier to spot π
Going back to the other thread probably better to spend time on ones worth looking for as even if you find a 1893/2 in that grade nobody will want it .
Maybe someone will have a clear picture for you to make your own opinion on them π
