If your card is returned as ungradable, that determination was made based on one of the following reasons:
N-1 Evidence of Trimming - When a card's edge appears to have been altered. A card doctor may use scissors, scalpel, cutter, or any other sharp instrument. A card that appears trimmed: A hooked appearance along the edge, unusually sharp or uncommon edges for the issue, an inconsistent tone to the color of the edge in question or a wavy, unnatural look to the edges.
N-2 Evidence of Restoration - When a card's paper stock appears to have been built up - for example, when ripped corners are built up to look like new corners.
N-3 Evidence of Recoloration - Where a card's color appears to have been artificially improved.
N-4 Questionable Authenticity - This is the term used when a card appears to be counterfeit or when the autograph is deemed to be not genuine.
N-5 Altered Stock - This includes, but is not limited to characteristics on the card that appear to show some form of alteration such as paper restoration, crease/wrinkle pressing or enhanced gloss.
N-6 Minimum Size Requirement - When a card is significantly undersized according to factory specifications. You will not be charged the grading fee.
N-7 Evidence of Cleaning - When a whitener is used to whiten borders or a solution is used to remove wax, candy, gum or tobacco stains.
N-8 Miscut - This term is used when the factory cut is abnormal for the issue, causing the card’s edges to deviate from their intended appearance. Grading fees are not charged in this instance.
N-9 Don't Grade - When we do not grade an issue. The cards may be oversized or an obscure issue. You will not be charged the grading fee.
N-0 Authentic Only - This means that PSA is only certifying that the item is genuine, without a numerical grade. This may be due to the existence of an alteration, one with malice or otherwise, a major defect or the original submitter may have requested that PSA encapsulate the card without a grade. The "Authentic" label means that the item, in our opinion, is real but nothing more.
AA Authentic Altered - This means that while PSA is certifying that the item is genuine, due to the existence of alterations, the item cannot receive a numerical grade. The term altered may mean that the card shows evidence of one or more of the following: trimming, recoloring, restoration, and/or cleaning. Items receiving the "Authentic Altered" designation, in our opinion, are genuine with the presence of some type of alteration. This is done on a case-by-case basis only, and must be notated on the submission form at the time of submission.
