It appears I made the mistake of photographing the card in its holder - those lines appear to be shadows from scratches in the holder, not on the card. If I hold the card in a light at an angle they vanish from the card completely. I should take it out of the holder and get photos. The holder has a load of little scratches on it right over that area and elsewhere. It's apparently seen quite a bit of action.
