leonI have several cards that have had pencil markings erased, you can not see WITHOUT a magnifying glass- as you said, and were downgraded in grade(s) OR were classifed "MK"....which is a serious detractor in grading....My personal opnion is that an almost undetectable indention should not ding a card too much....but I guess that's not how SGC and PSA see it....so your answer about the magnifying glass is correct....regards all (BTW, I think it was Jay Or Pete that told me about the architect's eraser which I called an "art" eraser)
