Grading cards is big business and an objective, trustworthy grading system is a necessity. The Professional Sports Authenticator (PSA) created the most common grading system, ranging from 10 to 1.

• 10: Gem Mint. The sports card is as perfect as possible. Corners are sharp, colour is glossy, and the card is free of any staining. The image is centred.

• 9: Mint. Only very minor flaws. Slightly off-centre, slight printing imperfection, but otherwise an excellent sports card.

• 8: Near Mint-Mint. Excellent sports card, slight fraying might be present. Slightly off-white borders.

• 7: Near Mint. Close inspection reveals slight surface wear or slightly frayed corners. Mostly glossy picture, slight printing errors.

• 6: Excellent-Mint. May have a printing defect or visible surface wear, but there is no loss of overall appeal.

• 5: Excellent. Minor corner rounding. Edges might have minor chipping. Minor noticeable surface scratches.

• 4: Very Good-Excellent. Slightly rounded corners, surface wear, some original gloss.

• 3: Very Good. Some rounded corners, slight surface scratches or scuffing.

• 2: Good. Several creases are apparent. Corners rounded. No gloss.

• 1: Poor to Fair. The sports card shows advanced wear. Corners are rounded, edges chipped and frayed. Pitting, chipping, and scuffing are all very apparent.

There are four main sports card grading and authentication services. The PSA, BGS, SGC, and GAI.

• Professional Sports Authenticators (PSA): PSA pioneered the grading scale detailed above. They are part of Collectors Universe, a publicly traded Nasdaq company. They have graded some of the most valuable sports cards ever sold and are an industry leader. However, you need a membership to take advantage of their grading directly; otherwise, you need to work through a dealer. PSA/DNA also has an online "QuickOpinion" program that allows potential buyers to have listings evaluated for a minimal cost. Within 24 to 36 hours PSA/DNA will return one of three opinions: "likely genuine," "unlikely genuine," or "cannot render an opinion."

• Beckett Grading Services (BGS): The BGS is affiliated with Beckett magazine and also uses a 10-point scale. What makes BGS unique is that it also offers a secondary rating for, say, corners or edges. Many people believe the BGS scale is graded more strictly than the PSA scale. eBay also teamed with Beckett to develop a "Value Guide" for sports cards, available at Beckett's Web site.

• Sportscard Guarantee (SGC): The SGC grading scale starts at 10 (poor) and goes up to 100 (pristine).

• Global Authentication, Inc. (GAI): The GAI was started by two former PSA employees and carries a lot of that prestige with it. In addition to sports cards, they also grade movie memorabilia.

Authentication services such as OnlineAuthentics.com and Sports Card Digest (SCD) also support the sports cards industry, complementing the work done by grading services.

Make sure you review eBay’s information on Opinions, Authentication & Grading and the Autographed Items policy before you place a bid or buy an item.

Remember: eBay does not review listings for authenticity or quality in any way. It is up to you to research the card you are interested in and the grading of that card before placing a bid or buying it.

Buying graded cards is a great way to round out your collection. Not only are you provided additional assurance of their quality, but most grading companies will seal your sports cards in a hard plastic case, helping to protect them from damage.

When buying graded cards on eBay, make sure the seller has all the original documentation that came with the card when it was graded. This will help to ensure that the card has been taken care of and that the grading is official. Always get more information about the grading of a card from the seller by using the Ask seller a question under the seller's profile on eBay.

When checking on the price of graded cards, do some research. The price of a card is dependent on the quality and the rarity of the card. Check to see how other similar cards of similar quality have sold on eBay. Were they able to get “book” value for them? More than book value?

The Web sites of many grading services often have population records to show the relative scarcity of a card in a given condition. You can use them, and the amount of listings you find on eBay, to determine if the card is very hard to find or fairly common.
