Card Grading Scale Explained: PSA, BGS, and CGC Numbers Decoded

Published March 24, 2026 • 22 min read

You've seen the numbers on slabbed cards—PSA 10, BGS 9.5, CGC 8—but what do they actually mean? And more importantly, why does a single number sometimes double or triple a card's price?

The card grading scale is the backbone of the entire graded card market. Whether you're buying your first slab, deciding which cards to submit, or trying to understand why a BGS Black Label 10 sells for more than a PSA 10, you need to understand how these numbers work. Not just the basics—the nuances that separate collectors who make smart decisions from those who learn expensive lessons.

Here's the thing: PSA, BGS, and CGC all use a 1-10 scale, but they don't grade the same way. Each company has different standards, different price structures, and different reputations in the market. A "10" doesn't mean the same thing everywhere. And once you understand the differences, you'll make better decisions about which cards to grade, which company to use, and what your graded cards are actually worth.

We're going to break down every grade, every subgrade, and every meaningful difference between the three major grading companies. Let's decode these numbers.


Why the Card Grading Scale Matters

At its core, the grading scale exists to standardize something subjective: how nice is this card? Before professional grading, buying a "near mint" card on eBay was a dice roll. One seller's "near mint" was another seller's "lightly played." There was no shared language.

Professional grading companies solved this by creating numbered scales with specific, published criteria. When you buy a PSA 10, you know exactly what condition standards that card met—regardless of who sold it to you or where it came from.

But the grading scale does more than standardize condition. It directly determines value. The difference between a PSA 9 and a PSA 10 on a desirable card isn't 10%—it's often 200-1,000%. Understanding the scale isn't just collector trivia. It's financial literacy for anyone buying, selling, or submitting cards.

Key insight: The grading scale isn't just about condition—it's about confidence. A graded card tells the buyer exactly what they're getting, which is why graded cards consistently sell for premiums over raw cards in equivalent condition.


The Complete PSA Grading Scale (1-10)

PSA (Professional Sports Authenticator) is the largest and most recognized grading company in the hobby. Their scale is straightforward: whole numbers only, from 1 to 10, with no half-points and no subgrades. You get one number on the label. That's it.

This simplicity is both a strength and a weakness. It's easy to understand, but it doesn't tell you why a card received its grade. A PSA 9 could have a centering issue, a soft corner, or a minor surface scratch—you'll never know which one from the label alone.

Grade Name What It Means
PSA 10 Gem Mint Virtually perfect. All four corners razor-sharp, edges clean, surface free of defects, centering within 60/40 front and 75/25 back. The gold standard.
PSA 9 Mint One minor flaw allowed. Could be a slightly soft corner, minor centering variance (65/35), or a tiny surface imperfection. Still an excellent card.
PSA 8 NM-MT (Near Mint–Mint) Minor wear visible on close inspection. Light edge whitening, slight corner softness, or minor surface wear. Most collectors consider this a strong card.
PSA 7 Near Mint Noticeable but not severe wear. Some corner fraying, visible edge whitening, minor surface scratches. A solid condition for vintage cards.
PSA 6 EX-MT (Excellent–Mint) Moderate wear becoming apparent. Visible corner rounding, noticeable whitening, possible light crease or surface wear.
PSA 5 Excellent Wear evident across multiple areas. Rounded corners, edge chipping, surface scratches, or centering well off standard. Still structurally sound.
PSA 4 VG-EX (Very Good–Excellent) Significant wear. Noticeable corner and edge damage, possible light creases, surface showing age. Card still intact and presentable.
PSA 3 Very Good Heavy wear. Rounded corners, major edge wear, creases may be present, surface damage visible. Common for well-loved vintage cards.
PSA 2 Good Severe wear. Major creasing, heavy corner and edge damage, surface heavily affected. Card is complete but shows significant use.
PSA 1 Poor Extreme damage. May have tears, holes, heavy staining, or missing pieces. The card exists—that's about the nicest thing to say.

PSA's Centering Standards

Centering is one of the most straightforward areas to evaluate, and PSA is relatively lenient compared to BGS. For a PSA 10, centering must be within 60/40 on the front and 75/25 on the back. That's actually quite generous—you can have visibly uneven borders and still land a 10 if everything else is perfect.

For reference, 60/40 means the wider border can be up to 1.5 times the narrower border. Most collectors eyeballing cards would notice this. PSA's centering requirements for a 9 are even more relaxed: 65/35 on the front and 90/10 on the back.

Pro tip: Use our free centering calculator to measure your card's centering ratio precisely from a photo. Knowing your exact centering numbers helps predict whether a card will meet PSA, BGS, or CGC standards.

PSA Pricing and Turnaround (2026)

PSA's most affordable tier starts at $24 per card with a turnaround of 150+ business days—that's roughly 7-8 months. Express tiers range from $50 (30 business days) up to $600+ for walk-through service (1-2 business days). Bulk submissions of 20+ cards at the value tier are the most cost-effective approach, but you'll be waiting a while.


The Complete BGS Grading Scale (1-10 with Subgrades)

BGS (Beckett Grading Services) takes a fundamentally different approach from PSA. Instead of a single number, BGS provides four individual subgrades that feed into the overall score. The scale also uses half-point increments (8.5, 9.5, etc.), giving more granularity than PSA's whole numbers.

The Four BGS Subgrades

📐 Centering

Measures border symmetry on front and back. BGS is stricter than PSA here—for a subgrade of 10, centering needs to be within 50/50 to 55/45 on the front and 75/25 on the back. Even slight imbalance gets dinged.

🔲 Corners

Evaluates sharpness and integrity of all four corners. Under magnification, BGS graders look for any fuzzing, rounding, dings, or peeling. A single slightly soft corner can drop this subgrade from a 10 to a 9.5 or 9.

📏 Edges

Checks all four edges for whitening, chipping, rough cuts, and layer separation. Dark-bordered cards are especially vulnerable—any whitening stands out. BGS examines edges under magnification on both front and back.

✨ Surface

The most subjective subgrade. Covers scratches, print lines, ink spots, fingerprints, holo scratches, and any other surface defects. BGS evaluates under specific lighting conditions designed to reveal imperfections invisible in normal viewing.

How BGS Calculates the Overall Grade

The overall BGS grade is not a simple average of the four subgrades. BGS uses a weighted calculation that considers all four subgrades, but the specifics aren't publicly disclosed. In general:

  • If all four subgrades are 9.5, the overall is 9.5
  • Three 9.5s and one 9 typically yields a 9.5 overall
  • Two 9.5s and two 9s usually gives a 9 overall
  • One low subgrade can drag the entire score down significantly

BGS Grade Tiers Explained

Grade Name Label Color What It Means
10 Pristine Gold All subgrades 9.5 or higher. The overall grade is 10 but individual subgrades can include 9.5s. Extremely rare and valuable.
10 Black Label Pristine (Perfect) Black ALL four subgrades are perfect 10s. The rarest and most valuable BGS grade. Less than 1% of submissions achieve this.
9.5 Gem Mint Gold The BGS equivalent to PSA 10 in market perception. High subgrades across the board with minimal imperfections.
9 Mint Silver Minor imperfections in one or more subgrades. Still an excellent card with strong market value.
8.5 NM-MT+ Silver Slightly better than 8 but not quite a 9. Multiple minor issues bringing individual subgrades down.
8 NM-MT Silver Visible wear on close inspection. Comparable to PSA 8 but with subgrade detail.
7 and below NM down to Poor Silver Increasing levels of wear and damage. Subgrades reveal specific problem areas.

The BGS Black Label: The Holy Grail

Let's talk about the Black Label because it's one of the most misunderstood grades in the hobby. A BGS Black Label 10 means every single subgrade—Centering, Corners, Edges, and Surface—is a perfect 10. The label itself is printed in black instead of gold, making it instantly recognizable.

Why does this matter? Because it's absurdly hard to achieve. BGS 10 Pristine (gold label) allows some subgrades to be 9.5—which is still exceptional. Black Label demands perfection across the board. For context, well under 1% of all cards submitted to BGS receive a Black Label. The card has to be essentially flawless under magnification from every angle.

The market reflects this rarity. A BGS Black Label 10 on a desirable card can sell for significantly more than a PSA 10—sometimes 2-5x more. For high-end cards, the Black Label premium is enormous. It's the ultimate flex in the graded card world.

BGS Pricing and Turnaround (2026)

BGS starts at $14.95 per card with a turnaround of 75+ business days—about 3-4 months. That's actually their most affordable option and faster than PSA's cheapest tier. Express services range from $35 (20 business days) to $125+ for premium turnaround. The subgrade detail you get with BGS is a significant value-add that many collectors find worth the wait.


The Complete CGC Grading Scale (1-10)

CGC (Certified Guaranty Company) entered the trading card grading market more recently, building on their established reputation in comic book grading. They've quickly gained traction, especially in the Pokémon and TCG communities, thanks to competitive pricing and faster turnaround times.

CGC uses a 1-10 scale with half-point increments, similar to BGS. However, CGC does not provide standard subgrades on the label—you get a single overall grade. They do offer an optional "subgrades" add-on for an extra fee, but it's not the default.

Grade Name What It Means
CGC 10 Pristine Virtually flawless. Perfect corners, edges, surface, and centering. Comparable to BGS 10 in strictness. The rarest CGC grade.
CGC 9.5 Gem Mint Near-perfect with only the most trivial imperfection. The CGC grade most comparable to PSA 10 in market treatment.
CGC 9 Mint One or two minor flaws. A strong card that missed the top tier by a small margin.
CGC 8.5 NM-MT+ Between Near Mint–Mint and Mint. Minor wear in multiple areas keeps it from a 9.
CGC 8 NM-MT Light wear visible under close inspection. Slight edge whitening, minor corner softness, or small surface marks.
CGC 7.5 NM+ Noticeable imperfections becoming visible without magnification. Still a well-preserved card.
CGC 7 and below NM down to Poor Increasing wear and damage. Same general standards as other companies for lower grades.

What Makes CGC Different

CGC has carved out a strong position in the market by doing a few things well:

  • Faster turnaround: Starting at approximately 40 business days for bulk, CGC is significantly faster than PSA's 150+ day economy tier
  • Competitive pricing: Bulk submissions start around $15 per card—between BGS and PSA on cost
  • Strong Pokémon/TCG acceptance: CGC has become especially popular in the Pokémon community, where their slabs trade at strong premiums
  • Tamper-evident cases: CGC's holders are well-regarded for security and durability

CGC Pricing and Turnaround (2026)

CGC's bulk tier starts at $15 per card (minimum 25 cards) with a 40 business day turnaround. Standard submissions (no minimum) start at $18 per card. Express services are available at higher price points. For collectors submitting larger quantities, CGC often offers the best value proposition in the market.

How Grades Affect Card Value

This is where the card grading scale gets real. The numbers aren't just descriptors—they're price multipliers. And the relationship between grade and value isn't linear. It's exponential at the top.

The Grade-Value Curve

For most cards, the value curve looks like a hockey stick. Grades 1-7 represent a relatively flat range of values. Then from 8 to 9, there's a moderate jump. From 9 to 10? It's often a 2x to 10x leap depending on the card's popularity and scarcity.

Here's why: the supply of 10s is dramatically lower than 9s. For popular modern cards, maybe 30-50% of submissions grade a PSA 10. But for older cards, especially from the late '90s, PSA 10 population can be under 5% of all graded copies. Scarcity drives price.

Real-World Value Examples

Card Raw PSA 8 PSA 9 PSA 10
Base Set Charizard (Unlimited) ~$200 ~$250 ~$350 ~$1,200
Prismatic Evolutions Umbreon ex SIR ~$120 ~$135 ~$180 ~$500+
2020 Panini Prizm Joe Burrow Base ~$30 ~$40 ~$55 ~$150
1st Edition Shadowless Charizard ~$25,000 ~$40,000 ~$80,000 ~$420,000+

Look at that 1st Edition Charizard progression. From PSA 9 to PSA 10, the price jumps over 5x. That single grade point represents $340,000 in value. This is why understanding the card grading scale—and having the tools to predict your grade accurately—is so critical.

The Break-Even Analysis

Not every graded card is worth more than a raw card. After factoring in grading costs, shipping, and insurance, you need a meaningful value increase to come out ahead. Here's the math for PSA's economy tier:

  • Grading cost: $24 per card
  • Shipping to PSA: ~$10-15 (split across cards)
  • Insurance: Varies by declared value
  • Return shipping: ~$10-15
  • Total cost per card: Roughly $30-40

If a card is worth $20 raw and comes back a PSA 8 worth $25, you've lost money. This is why we always recommend pre-screening your cards before committing to professional grading. Whether you inspect cards at home manually or use AI tools, knowing what to expect saves you real money.


When to Choose Each Grading Company

There's no universally "best" grading company. The right choice depends on what you're trying to accomplish. Here's our honest take.

Choose PSA When...

  • Maximum resale value is the goal. PSA-graded cards command the highest premiums in the sports card market and remain the gold standard for Pokémon. If you're grading to sell, PSA is the safest bet for top dollar.
  • You have a small number of high-value cards. PSA's premium tiers (faster turnaround) make sense when you have a few cards worth hundreds or thousands.
  • Simplicity matters. One number, universally recognized. Buyers know exactly what PSA 10 means.
  • You're grading sports cards. PSA dominates sports card grading. The market premium for PSA-graded sports cards is substantially higher than BGS or CGC equivalents.

Choose BGS When...

  • You want to know exactly what's wrong (or right) with your card. The four subgrades tell you precisely where a card excels and where it falls short. This is invaluable information.
  • You're chasing a Black Label. If you have a card that you believe is truly flawless—perfect centering, perfect everything—BGS is the only company that can certify that with a Black Label. The premium is real.
  • You appreciate granularity. Half-point grades mean a BGS 9.5 can capture cards that are better than a PSA 9 but might not quite hit PSA 10. Less gets lost in translation.
  • You have patience but want value. BGS's $14.95 base tier is the cheapest among the big three, though the 75+ day wait requires patience.

Choose CGC When...

  • You're grading in bulk. CGC's bulk pricing ($15/card, 25 minimum) combined with the fastest economy turnaround (40 business days) makes them ideal for large submissions.
  • Speed matters. CGC consistently delivers the fastest turnaround at every price point. If waiting 5+ months for PSA isn't in the cards (pun intended), CGC gets your slabs back sooner.
  • You're primarily grading Pokémon or TCG cards. CGC has built exceptional market acceptance in the Pokémon community. CGC-graded Pokémon cards trade at competitive premiums—sometimes approaching PSA prices.
  • Budget is a priority. For collectors who want professional grading without PSA's cost and wait, CGC hits the sweet spot of quality, price, and speed.

Our recommendation: Don't be a one-company collector. Use PSA for your highest-value sports cards, BGS when you want subgrade detail or a Black Label shot, and CGC for bulk Pokémon/TCG submissions. Match the company to the card and situation.


Pre-Screening: Estimate Your Grade Before You Submit

Here's where all this grading scale knowledge becomes actionable. Once you understand what each grade means and what the grading companies are looking for, you can start estimating grades yourself—and make much smarter submission decisions.

Manual Inspection Approach

With good lighting, a jeweler's loupe (10x-20x), and the grading criteria above, you can visually evaluate each of the four key areas:

  1. Corners: Use your loupe to check all four corners on both sides. Any fuzzing or rounding? If yes, you're likely looking at a 9 or below.
  2. Edges: Run your eye along every edge. Whitening on dark-bordered cards? Rough factory cuts? These are common grade killers.
  3. Surface: Tilt the card under direct light at multiple angles. Holo scratches, print lines, and fingerprints only appear at certain angles. This is the hardest area to evaluate.
  4. Centering: Measure borders with a ruler or use our free centering calculator for precise ratios.

AI-Powered Pre-Screening

Manual inspection works, but it has limits. Your eyes tire. Lighting varies. And most of us don't have the thousands of hours of training that professional graders have.

This is where AI card grading tools come in. Modern computer vision can analyze a high-resolution photo of your card and evaluate all four grading criteria with impressive precision. The best tools provide individual subgrade estimates for corners, edges, surface, and centering—giving you the same breakdown a BGS slab would show, but in minutes instead of months.

The practical benefit is clear: instead of guessing which cards in your collection are worth submitting, you get data-driven predictions. Submit the cards AI identifies as strong 9-10 candidates. Hold back the ones that need better condition to justify grading costs.

Frequently Asked Questions

What does the card grading scale mean?

The card grading scale is a 1-10 rating system used by professional grading companies (PSA, BGS, CGC) to evaluate a trading card's condition. A 1 represents a card in poor condition with major damage, while a 10 represents a virtually perfect or gem mint card. Each number corresponds to specific condition standards covering corners, edges, surface quality, and centering. The higher the number, the better the condition—and typically the higher the value.

What is the difference between PSA 10 and BGS 10?

They're similar in concept but different in execution. PSA 10 (Gem Mint) is a single overall grade with no subgrades—it allows centering up to 60/40 on the front, which is relatively lenient. BGS 10 (Pristine) is stricter, requiring near-perfect scores across all four subgrades (Centering, Corners, Edges, Surface). A regular BGS 10 allows some subgrades to be 9.5, while a BGS Black Label 10 requires ALL four subgrades to be perfect 10s. Black Labels are significantly rarer than PSA 10s and often command higher prices.

What is a BGS Black Label?

A BGS Black Label is the highest grade Beckett can assign. It means the overall grade is a 10 and all four individual subgrades (Centering, Corners, Edges, Surface) are also perfect 10s. The label is printed in black instead of gold, making it instantly recognizable. Black Labels are extremely rare—well under 1% of submissions achieve this—and they frequently sell for more than PSA 10 equivalents of the same card.

Is CGC grading as good as PSA or BGS?

CGC is a legitimate, well-respected grading company with consistent standards comparable to PSA and BGS. They tend to be more affordable ($15+ for bulk) with significantly faster turnaround times (40+ business days vs. PSA's 150+). CGC-graded cards command slightly lower market premiums than PSA for most sports cards, but the gap is narrowing rapidly for Pokémon and TCG cards. For bulk submissions and Pokémon collectors, CGC is often the best value.

How do card grades affect value?

Card grades have a massive, non-linear impact on value. The difference between a PSA 9 and PSA 10 typically represents a 2-10x price increase depending on the card. For iconic cards like a 1st Edition Charizard, the PSA 10 sells for 5x+ more than a PSA 9. Lower grades (7 and below) often don't recoup grading costs for most modern cards. The grade is essentially a value multiplier—and the multiplier gets exponentially larger as you approach a perfect 10.

Which grading company should I use?

It depends on your goals. Choose PSA for maximum resale value, especially for sports cards. Choose BGS if you want detailed subgrades showing exactly where your card excels and falls short, or if you're chasing a Black Label premium. Choose CGC for budget-friendly bulk grading with the fastest turnaround, especially for Pokémon and TCG cards. Many smart collectors use different companies for different cards.

Can I estimate my card's grade before submitting?

Absolutely. You can visually inspect corners, edges, surface, and centering at home using a jeweler's loupe and bright, direct lighting. For more precise estimates, AI-powered tools like CardGrader.AI analyze high-resolution photos and provide detailed grade predictions with subgrade breakdowns—helping you identify which cards are worth the professional grading investment before you spend a dime.
