Single cards

Single cards condition description:

• MINT - A mint card is in perfect condition; no excuses. This means, that the front is in perfect condition, there are no scratches on the surface, and the surface is perfectly clean. For the back it means, that the card is indistinguishable from cards of a newly openend booster. If a card has a signature or a Grand Prix stamp it can never be graded Mint, even if the card stock is otherwise in Mint condition.
• NM - A Near Mint card looks like it has never been played without sleeves. Small allowances can be made, but the card generally shows no wear.The border of NM card can have small white spots, but they must be very few and very small. When the card is inspected under bright daylight, the surface must generally appear clean. It can have a few minor spots, but scratches can never be allowed for NM cards.
• Excellent - An Excellent cards look like it was used for a few games without sleeves. For Excellent cards it is almost always clearly visible upon first inspection that the card is not in perfect condition. However, although the damage is clearly visible it is only of minor severity.
• Good - Cards in Good condition usually show strong wear all around the card. The edges and corners have many white spots, the surface usually has scratches and the card usually has accumulated some dirt on its surface. However, the card still only has damage that stems from regular play. The card has no water damage or bends whatsoever.
•  Light played - A Light Played card is clearly legal for play in a sleeved deck. It has also not been tampered with (inked border, random scribblings on the card etc.). If both of these criteria apply the card may look very bad, but it can be graded Light Played.
•  Played - A Played card looks extremely bad, and it is doubtful if the card is tournament legal even in a sleeved deck. However, the card has not been tampered with otherwise (inked border, random scribblings on the card etc.).
•  Poor - A Poor card has damage that cannot normally have stemmed from regular use of the card.
