FWIW I haven't seen a surface crease yet that can't be detected at a pixel level - but that would corroborate with numbers from physical card a training data meaning the human can inspect it in anyway to provide the grades associated w the image. In this way - there are no gaps between eyes and lens. The only thing that might get missed in this dual training model is a stain or
mark that only exists on the edge of the card but doesn't show on the front or back when looking at the edges. I've only been able to produce this on extremely thick cards like the modern memorabilia/insert stuff - but in okay not worrying to much about that case right now...
