    I'd go with "nose grease"; the judicious application of skin oil to the surface.

    I put Altered surface, but specifically "Wheel Marks" That has gotten me a couple of times, very hard to spot.

    Using a HALOGEN makes these pesky marks more visible.

    I think there are subtleties for each of these examples that make any one of them difficult to detect. Removal of verdigris on a Large Cent using Blue Ribbon and a rose thorn can be barely imperceptible... use vise grips and a brillo pad, not so much.

    I think I have missed this at least 3 times myself! Only when I really looked for them, did I find them.

    I would say 'altered surface', followed by 'questionable color'.... Cheers, RickO

    When I browse coins for potentials, if the slab says REMOVED FROM MOUNT, I try to find the evidence.
    Granted, I am not seeing the actual rim but some of the work is very very good.
