The £20,000 Difference Between PSA 9 and PSA 10
I own a Base Set Charizard. It’s not 1st Edition. It’s not Shadowless. It’s a regular unlimited print from 1999 that millions of people own.
If it grades PSA 9, it’s worth approximately £800 to £1,200. If it grades PSA 10, it’s worth £15,000 to £25,000. Same card. One grade point difference. 20x value multiplier.
This is the grading game. A subjective assessment by a grader who spends 30 seconds examining your card determines whether you’ve got a nice collectible or a down payment on a car.
This chapter explains grading economics (when grading adds value, when it destroys value), how to pre-grade your own cards to avoid expensive disappointments, which grading company to use for different scenarios, and the harsh reality that most cards you think are PSA 10 candidates aren’t.
By the end, you’ll understand why condition is the most important value driver for vintage cards, how to properly evaluate condition yourself, and when to send cards for grading versus when to keep them raw.
Grading Companies: Who They Are and What They Do
PSA (Professional Sports Authenticator)
Market position: Industry leader, most recognised brand, highest premiums for PSA 10s
Grading scale: 1 to 10, whole numbers only (no half grades)
Turnaround time: 20 to 90+ days depending on service level
Cost: £20 to £150+ per card depending on declared value and service speed
Best for: Vintage cards (WOTC era), high value cards where PSA 10 premium justifies cost, cards you plan to sell (PSA has highest market recognition)
Weaknesses: No subgrades (you don’t know why card got the grade it did), inconsistent grading standards (same card submitted twice might get different grades), expensive for bulk submissions
BGS (Beckett Grading Services)
Market position: Second most recognised, preferred by some vintage collectors
Grading scale: 1 to 10 with half grades (9.5 exists), provides subgrades for centering, edges, corners, surface
Turnaround time: Similar to PSA
Cost: Similar to PSA
Best for: Cards where you want detailed feedback (subgrades tell you exactly what’s wrong), modern cards where BGS Black Label 10 (perfect 10 in all subgrades) commands premium
Weaknesses: Lower market premium than PSA for most cards, BGS 9.5 often sells for less than PSA 10 despite being theoretically similar grade
CGC (Certified Guaranty Company)
Market position: Newer to Pokémon (established in comics/coins), growing acceptance
Grading scale: 1 to 10 with half grades, provides subgrades
Turnaround time: Often faster than PSA/BGS
Cost: Generally cheaper than PSA for same service level
Best for: Modern cards, budget grading, cards where you want subgrades but don’t need PSA premium
Weaknesses: Lower market recognition, lower resale premiums compared to PSA, less established in vintage market
Which Company Should You Use?
Vintage WOTC cards worth £200+ raw: PSA (market demands it for maximum value)
Modern cards: CGC (cheaper, faster, subgrades helpful) or PSA (if chasing maximum resale value)
Cards you’re keeping forever: BGS or CGC (subgrades are interesting for personal knowledge)
Bulk submissions: CGC (better pricing for volume)
The Four Components of Card Condition
Professional graders evaluate four aspects. Understanding these helps you pre-grade your cards before submission.
Centering (30% to 40% of Grade Weight)
What it is: The alignment of the card’s image within the borders. Measured by comparing left/right borders and top/bottom borders.
PSA 10 standard: 60/40 or better front, 75/25 or better back (meaning borders can be slightly off but not dramatically)
How to measure: Use a ruler or centering tool. Measure left border, measure right border. If left is 3mm and right is 5mm, that’s 3:5 or 60:40 ratio. Acceptable for PSA 10.
Common issue: WOTC era cards are notoriously off centre. Finding a perfectly centred Base Set card is difficult. This is why well centred vintage commands premiums.
Modern cards: Generally better centred due to improved printing technology, but errors still happen.
Reality check: If your card is visibly off centre to the naked eye (one border clearly thicker than opposite border), it’s not getting PSA 10. Don’t waste grading fees.
Edges (20% to 30% of Grade Weight)
What it is: The condition of the card’s four edges. Looking for whitening, chipping, fraying, or wear.
PSA 10 standard: Clean, sharp edges with no visible whitening under 10x magnification.
How to inspect: Under bright light, examine each edge at an angle. Any white showing through the colored edge indicates wear.
Common issue: Edge whitening from shuffling, friction in binders, or improper storage. Dark bordered cards (many WOTC holos) show whitening more obviously.
Prevention: Double sleeve cards immediately upon opening. Never shuffle valuable cards. Use perfect fit sleeves inside regular sleeves.
Reality check: If you can see edge whitening with naked eye, expect PSA 8 or lower. Even minor whitening visible under magnification prevents PSA 10.
Corners (20% to 30% of Grade Weight)
What it is: Sharpness and integrity of the four corners. Looking for rounding, bending, whitening, or damage.
PSA 10 standard: Sharp, pristine corners with no wear visible under 10x magnification.
How to inspect: Examine each corner under magnification. Even slight softness or micro bending visible under magnification disqualifies PSA 10.
Common issue: Corner damage from binders (cards sliding in/out), improper storage, or handling. Once corners are damaged, there’s no fixing it.
Prevention: Use top loaders for valuable cards. Never store in tight binders where cards rub. Handle cards by edges only.
Reality check: Run your finger gently across each corner. If you feel any softness or rounding, it’s not PSA 10.
Surface (20% to 30% of Grade Weight)
What it is: The card’s face and back surface. Looking for scratches, print lines, indentations, stains, or other defects.
PSA 10 standard: No surface defects visible under 10x magnification. This includes factory print lines, which are common and disqualify PSA 10.
How to inspect: Under bright light at an angle, slowly rotate card to catch any scratches, print lines, or surface irregularities. Holofoil cards are particularly susceptible to showing surface defects.
Common issues:
- Holofoil scratches from shuffling or touching
- Print lines (factory defects, particularly common in certain sets)
- Indentations from being stacked improperly
- Fingerprints or oil residue
Prevention: Never touch holofoil surface. Handle cards by edges. Store in sleeves immediately.
Reality check: If you see any scratches on holo surface with naked eye, it’s PSA 9 at best. Print lines automatically disqualify PSA 10 even if everything else is perfect.
Grading Economics: When It Makes Financial Sense
The Break Even Calculation
Grading cost: £25 average (including shipping, insurance, service fee)
Card must be worth minimum £100 raw to justify grading because:
- If it grades PSA 8 or 9, graded value might be similar to raw value
- You’ve invested £25 with minimal return
- If it grades PSA 7 or lower, you’ve lost money (grading cost + reduced value from confirmed low grade)
Sweet spot for grading: Cards worth £200+ raw where PSA 10 would be worth £1,000+. The upside justifies the risk.
Expected Grade Distribution
For cards you think are PSA 10 candidates, realistic outcomes:
- 5% to 10% actually get PSA 10
- 40% to 50% get PSA 9
- 30% to 40% get PSA 8
- 10% to 20% get PSA 7 or lower
This means: If you submit 10 cards you believe are PSA 10s, expect 1 actual PSA 10, 4 to 5 PSA 9s, 3 to 4 PSA 8s, and 1 to 2 disappointments.
At £25 per card, that’s £250 total cost for grading. Did the results justify the expense?
When NOT to Grade
- Cards worth less than £100 raw (grading cost kills ROI)
- Cards with visible flaws (you know it won’t grade high, don’t pay to confirm)
- Modern cards from recent sets (supply is high, graded premium is low)
- Cards you’re keeping forever (unless you want the slab for protection/display)
- Cards where raw NM sells for similar to PSA 8/9 graded (grading adds no value)
When TO Grade
- Vintage WOTC cards in apparent NM/Mint condition worth £200+ raw
- Cards where PSA 10 commands 5x to 10x premium over PSA 9
- High value cards where authentication is important (prevents counterfeit concerns)
- Cards you plan to sell where graded premium justifies cost
How to Pre-Grade Your Cards (Avoid Expensive Mistakes)
The Self-Assessment Process
Step 1: Initial visual inspection
- Is centering visibly off? (Disqualifies PSA 10)
- Any edge whitening visible? (Disqualifies PSA 10)
- Any corner wear visible? (Disqualifies PSA 10)
- Any surface scratches on holo? (Disqualifies PSA 10)
If you answered yes to any, don’t grade expecting PSA 10.
Step 2: Magnified inspection (10x loupe)
- Measure centering with ruler
- Check each edge for micro whitening
- Examine each corner for softness
- Scan surface for print lines, scratches, indentations
Step 3: Honest self-assessment
- PSA 10: Perfect in all aspects under magnification
- PSA 9: Minor imperfection in one area, everything else perfect
- PSA 8: Multiple minor imperfections or one moderate issue
- PSA 7 or lower: Visible issues without magnification
Step 4: Conservative estimation
Whatever grade you think the card deserves, subtract one grade. If you think it’s PSA 10, assume PSA 9. If you think PSA 9, assume PSA 8.
Graders are more critical than collectors. What you see as minor might be disqualifying to them.
Common Self-Grading Mistakes
Mistake 1: Ignoring centering
“The card looks perfect!” but it’s 70/30 centred. Maximum PSA 9.
Mistake 2: Missing print lines
Factory print lines are common on certain sets (Base Set, Jungle, Fossil). They’re visible under angled light. They disqualify PSA 10.
Mistake 3: Overestimating holo condition
Holofoil scratches are everywhere on played cards. Even cards that “look clean” often have micro scratches that prevent PSA 10.
Mistake 4: Not checking the back
Back condition matters equally. Many collectors focus on front, forget to inspect back centering, edges, corners, surface.
Storage and Preservation: Protecting Your Investment
Proper Storage Hierarchy
Level 1 (Minimum protection): Penny sleeve
- Cost: 1p per sleeve
- Protection: Minimal (protects from fingerprints, light scratches)
- Use case: Bulk commons, cards worth £1 or less
Level 2 (Standard protection): Penny sleeve + regular sleeve
- Cost: 5p to 10p total per card
- Protection: Good (double barrier against scratches, moisture)
- Use case: Cards worth £5 to £50
Level 3 (Enhanced protection): Perfect fit inner sleeve + regular outer sleeve
- Cost: 15p to 20p total per card
- Protection: Excellent (tight fit prevents movement, double protection)
- Use case: Cards worth £50 to £200, cards you might grade
Level 4 (Maximum protection): Perfect fit + regular sleeve + top loader or card saver
- Cost: 30p to £1 per card
- Protection: Maximum (rigid protection prevents bending, sealed from elements)
- Use case: Cards worth £200+, grading candidates, display pieces
Environmental Factors
Temperature: Store at 15°C to 21°C. Avoid attics (too hot) and basements (too cold/humid).
Humidity: 30% to 50% relative humidity. Too humid causes warping and mold. Too dry causes brittleness.
Light: Avoid direct sunlight (causes fading, especially on older cards). UV light degrades card stock over time.
Storage containers:
- Avoid rubber bands (cause indentations)
- Avoid tight binders (friction damages edges)
- Use acid-free storage boxes
- Use binders with D-rings (not O-rings which create pressure points)
Handling Best Practices
- Wash and dry hands thoroughly before handling
- Hold cards by edges only, never touch surface
- Use cotton gloves for extremely valuable cards
- Work over soft surface (card mat, playmat) in case of drops
- Never eat or drink whilst handling valuable cards
- Remove cards from storage only when necessary
The Grading Submission Process
Step 1: Select Cards to Submit
- Pre-grade each card honestly
- Only submit cards worth £100+ raw
- Only submit cards you assess as PSA 9+ candidates
- Group by declared value tier (PSA charges more for high value cards)
Step 2: Package Properly
- Place each card in card saver (semi-rigid holder, cheaper than top loader and preferred by graders)
- Seal card saver with painter’s tape (not regular tape which damages)
- Wrap in bubble wrap
- Ship in rigid mailer with “DO NOT BEND” marking
- Insure for full declared value
Step 3: Wait (And Wait)
- Standard service: 60 to 90 days
- Express service: 20 to 30 days (costs 2x to 3x more)
- Super express: 5 to 10 days (costs 5x to 10x more, only worth it for extremely high value cards)
Step 4: Results
If cards grade as expected or better: Success! Consider selling whilst market is strong or holding for appreciation.
If cards grade lower than expected: Learn from it. Compare graded cards to your pre-grade assessment. Understand what you missed. Apply learnings to future submissions.
If considering re-grading (cracking and resubmitting): Only worthwhile if:
- Card graded PSA 9, you genuinely believe it’s PSA 10
- PSA 10 premium justifies £25+ additional grading cost plus risk of lower grade on resubmission
- You understand you might get PSA 8 on resubmission (grading is subjective)
Should You Grade Your Collection?
Grade If:
- You own vintage WOTC cards in apparent NM/Mint condition worth £200+ raw
- You plan to sell and graded premium justifies cost
- You want authentication for high value cards
- You want permanent protection (graded slabs prevent future damage)
Don’t Grade If:
- Cards are worth less than £100 raw
- You’re keeping cards forever and don’t care about resale value
- Cards have visible flaws (you know they won’t grade high)
- You can’t afford to lose the grading fee on disappointing grades
The Realistic Approach
Most collectors should:
- Keep 90% of collection raw (properly stored for protection)
- Grade the top 10% (highest value cards where grading adds significant premium)
- Accept that grading is expensive and results are unpredictable
- Focus on buying already-graded cards when possible (let others take the grading risk)
Final Thoughts: Condition Is King
In vintage Pokémon card collecting, condition is the primary value driver. A PSA 10 common can be worth more than a PSA 6 rare. A well centred, pristine vintage holo is exponentially more valuable than a played copy of the same card.
Understanding grading helps you:
- Make informed buying decisions (is this card worth the asking price given its condition?)
- Protect your collection properly (storage methods that preserve condition)
- Avoid expensive grading mistakes (submitting cards that won’t grade high)
- Recognise value when you see it (spotting underpriced high grade candidates)
You don’t need to grade every card. But you do need to understand condition assessment, because condition determines value more than any other factor in vintage collecting.
