Grading baseball cards can dramatically increase value — or waste money if done incorrectly.
Whether you’re submitting to Professional Sports Authenticator (PSA), Sportscard Guaranty Company (SGC), or Beckett Grading Services (BGS), preparation matters more than most beginners realize.
This guide walks through:
- How to decide if a card is worth grading
- How to inspect it properly
- The exact tools you should own
- How to prep the physical card
- Submission tips for each grading company
If you follow this checklist, you dramatically increase your odds of maximizing value.
Step 1: Decide If the Card Is Worth Grading
Before you touch a penny sleeve, evaluate the fundamentals.
Ask Yourself:
- Is it a Rookie Card?
- Is it a 1st Bowman?
- Is it low-numbered or short printed?
- Is it a top prospect or established star?
- Does a PSA 10 command a strong premium?
Rule of Thumb:
If a PSA 9 doesn’t justify grading fees, think carefully before submitting.
Modern grading (after shipping, insurance, and fees) often costs $25–$40 per card at minimum.
Step 2: Proper Card Inspection (The Most Important Step)
Grading is about four things:
- Centering
- Corners
- Edges
- Surface
You need proper lighting and patience.
Recommended Inspection Tools
5 Essential Tools for Beginners
1. Cotton or Nitrile Gloves
- Prevent fingerprints
- Avoid skin oils
- Especially important for chrome cards
2. Microfiber Cloth
- Gently wipe surface dust
- Never use paper towels
- Never use chemicals
3. Centering Tool (Card Ruler)
- Measures border ratios
- Helps estimate PSA 9 vs PSA 10 potential
- Critical for modern cards
4. 10x Loupe or Magnifier
- Detect micro surface scratches
- Identify corner whitening
- Spot print lines
5. Bright LED Light
- Tilt card under light
- Surface flaws appear instantly
These tools cost under $50 total and can save hundreds in bad submissions.
Step 3: Inspecting Each Grading Category
1. Centering
PSA allows:
- 60/40 front centering for a 10
- 75/25 for a 9
BGS is stricter. SGC is consistent but unforgiving on extreme imbalance.
Use your centering tool and measure both:
- Left to right
- Top to bottom
Chrome cards often appear centered but are slightly off when measured.
2. Corners
Look for:
- Whitening
- Soft tips
- Fraying (paper cards)
- Micro-dings (chrome)
Tilt under light — corner damage hides in normal lighting.
Even tiny corner wear usually drops a card to PSA 9.
3. Edges
Dark-bordered cards (especially black refractors) show chipping easily.
Check:
- All four edges
- Front and back
Chrome cards are notorious for:
- Edge flaking
- Factory roller marks
4. Surface
Surface is where most 10s die.
Check for:
- Print lines
- Scratches
- Indentations
- Dimples
- Fingerprints
- Roller marks
Tilt the card slowly under LED light.
If you can clearly see a flaw, graders will too.
Step 4: Prepping the Physical Card for Submission
This is where beginners often make mistakes.
Handling & Cleaning
- Wash hands or wear gloves
- Gently wipe with microfiber
- Do NOT polish
- Do NOT attempt to “fix” corners
- Do NOT use moisture
You are removing dust — not altering the card.
Proper Holders for Submission
Required:
- Penny sleeve
- Semi-rigid holder (Card Saver 1 preferred)
Do NOT Use:
- Top loaders
- One-touch magnetic holders
- Screw-down cases
Grading companies will remove cards from incorrect holders and may charge extra.
Packing Your Cards Safely
- Place cards in submission order
- Stack neatly
- Light rubber band (not tight)
- Sandwich between cardboard
- Bubble wrap
- Use sturdy box
- Always insure shipment
Never use padded envelopes.
Submitting to PSA
Why Choose PSA?
Professional Sports Authenticator
- Highest resale premiums
- Strongest modern liquidity
- Industry leader
PSA Submission Checklist
- Create account
- Choose service level

PSA is slightly more forgiving on centering but strict on surface.
Submitting to SGC
Why Choose SGC?
Sportscard Guaranty Company
- Fast turnaround

Often slightly cheaper than PSA.
Submitting to BGS
Why Choose BGS?
Beckett Grading Services

- Chance at Black Label 10
- Preferred by some ultra-modern collectors
BGS is the strictest on centering.
Common Beginner Mistakes
- Grading off-center cards hoping for 10
- Ignoring surface scratches
- Overgrading your own card
- Submitting low-value cards
- Not checking PSA 9 price before submitting
Final Grading Strategy for Beginners
If flipping:
- Grade only cards with strong PSA 10 upside
- Avoid marginal condition cards
- Focus on liquid players
If collecting:
- Grade PC cards for protection
- Don’t obsess over 10s
- Buy the card, not the grade

Recommended Grading Prep Tools
If you’re serious about grading consistently and maximizing gem rates, investing in a few inexpensive tools can dramatically improve your results.
Below is a beginner-friendly toolkit that I personally recommend for collectors preparing submissions.
Disclosure: As an Amazon Associate, I earn from qualifying purchases. These tools cost very little and can save you from expensive grading mistakes.
Cotton or Nitrile Gloves
Handling raw cards with bare hands transfers oil to the surface. On chrome and refractor finishes, this can result in fingerprints that lower grades.
What to look for:
- Lightweight cotton gloves or powder-free nitrile gloves
- Snug fit for better control
- Lint-free material
Recommended for:
- Chrome cards
- Black-bordered cards
- High-value submissions
Microfiber Cleaning Cloth
A microfiber cloth removes dust and loose debris without scratching the surface.
Use it to:
- Gently wipe chrome finishes
- Remove surface dust before submission
- Eliminate visible lint
Never use:
- Paper towels
- Tissues
- Chemical cleaners
- Polishing compounds
The goal is dust removal — not surface alteration.
Card Centering Tool
Centering is one of the fastest ways to eliminate a potential PSA 10.
General guidelines:
- PSA allows approximately 60/40 centering for a 10
- BGS is typically stricter
- Severe imbalance caps the grade regardless of surface quality
A centering tool removes guesswork and prevents wasted submissions.
If you cannot measure it, you are estimating — and estimation costs money.
10x Jeweler’s Loupe
Surface flaws are the most common reason modern cards grade a 9 instead of a 10.
Use a 10x loupe to detect:
- Micro-scratches
- Edge chipping
- Corner whitening
- Print lines
- Indentations
If you can see it under magnification, assume a grader can see it as well.
This tool quickly separates submission-worthy cards from marginal ones.
