@JustHereForPikachu asks
should I photograph the cards before they go out for grading or is that unnecessary?
Jeff answers
I would. Clear front, back, and detail photos give you a record of the exact cards you sent and their visible condition. Keep those with the submission details and shipping records. Photos won't predict or override the grade; they're simply useful documentation of what left your hands.
