Peter_SpaethSays a crease OR wrinkle cannot be pressed out.  So at least on the face of it there is still a disparity between PSA's published standards and Doug's statement regarding what PSA considers acceptable.  Hopefully his letter will clarify the situation.  Personally I would be surprised to see PSA publicly endorse pressing out even light wrinkles or laying down corners, but I don't profess to know how they view these things.  EDITED TO ADD unless I am not looking in the right place SGC does not define "altered" on its website.
