PSA vs BGS vs SGC: What the Grade Means for Your Offer

If you have graded cards to sell, the label on the slab does most of the talking. But the three major grading companies do not speak quite the same language. This guide explains what grading is, how PSA, BGS, and SGC differ, why one point on the scale can change an offer so much, and when grading a raw card is worth the money.

What grading is

Grading is a paid service. You send a card to a company. An expert checks that it is authentic, examines its condition, assigns a number, and seals it in a hard plastic case with a label. The label shows the card, the grade, and a certification number that anyone can look up.

Grading does two things for a seller. It removes the argument about authenticity. And it removes most of the argument about condition.

All three companies use a 1 to 10 scale, with 10 as the best. The details are where they differ.

How PSA, BGS, and SGC differ

PSA is the largest and most widely traded grading company. Grades run 1 through 10, with half-point grades in the middle of the scale. A PSA 10 is Gem Mint. A PSA 9 is Mint. The slab has a red-and-white label. PSA sometimes adds a qualifier such as OC for off-center or MK for a mark. A qualifier means the card would have graded higher if not for that one flaw, and cards with qualifiers usually sell for less than the same number without one. Because PSA has graded the most cards, it has the deepest pool of sold prices, which makes PSA slabs the easiest to value and often the most liquid.

BGS, from Beckett, uses the same 1 to 10 scale but adds four subgrades: centering, corners, edges, and surface. The subgrades are printed on the label, so a buyer can see exactly why a card is a 9 and not a 9.5. BGS has two kinds of 10. A gold-label Pristine 10 is a top grade. A Black Label 10 means all four subgrades are perfect, and those are much rarer. BGS 9.5 Gem Mint is the grade you will see most often on strong modern cards.

SGC also uses 1 to 10 with half points. Its slab has a black insert that many collectors like for vintage cards. SGC used a 100-point scale for years and moved to the 10-point scale in 2021, so you may still see older slabs with numbers like 96 or 88. SGC has a strong reputation for pre-1980 cards.

Why a 10 versus a 9 matters so much

Here is the part that surprises most sellers. The jump from a 9 to a 10 is almost never the same as the jump from an 8 to a 9. It is usually much bigger.

Two reasons. First, scarcity. Far fewer cards earn a 10, so the supply at the top is thin. Second, demand. Collectors who chase the best copy of a card compete for that small supply. Put those together and the top grade can be worth several times the grade just below it.

You can see this yourself. Search eBay sold listings for a card at each grade and compare. Sites like 130point gather completed sales in one place. Then look at the PSA, BGS, or SGC population report to see how many exist at each level. A card with thousands of 9s and a handful of 10s will show a steep gap.

Do not assume the three companies' grades are interchangeable. A 10 from one company does not always trade at the same level as a 10 from another, even for the same card. Check sold prices for the exact slab you have.

When grading is worth the fee, and what to do with raw cards

Grading costs money and takes time. It makes sense when the card has real value and the condition is strong enough that a high grade is likely. A valuable rookie card with sharp corners and good centering is a reasonable candidate.

It does not make sense when the card is common, when the fee is close to the card's value, or when the card has an obvious flaw. A creased card will not become more valuable by being graded a 3.

Be honest about condition. Look at the corners under good light. Check centering by comparing the borders. Tilt the card to find surface scratches. If you see a problem, a grader will see it too.

Most people should not grade before selling. Bring raw cards as they are and let a buyer evaluate them. A good buyer will tell you which cards, if any, would benefit from grading. Keep raw cards in sleeves and rigid holders if you have them. Do not clean them, and do not try to improve the corners. Any alteration is worse than the original flaw.

How buyers verify cert numbers

Every slab has a certification number on the label. PSA, BGS, and SGC each have a public lookup where that number can be entered. The lookup shows the card, the grade, and in some cases an image. Many newer labels also carry a QR code that does the same thing.

A buyer checks the number to make sure the label matches the card inside, the grade matches the record, and the slab has not been tampered with. It protects you as much as the buyer, because it confirms what you are selling.
