1 - Learn How to Evaluate Your Card's Condition
Before you even think about selling your card or submitting it for grading, evaluating its condition is step one—and it’s critical. Even the smallest flaw can significantly drop the card’s value. A near-mint card might sell for $50, while a gem mint version of the same card could bring in $500 or more.
Professional graders (like PSA, BGS, and SGC) and collectors all look at four core categories when judging condition:
🔹 Corners
Corners are often the first thing the eye notices—and the easiest place for damage to show. You want four sharp, crisp corners with no bending, whitening, or fraying.
Look for these imperfections:
- Rounded corners caused by mis-handling or improper storage
- White spots or “fuzz” at the tips, especially on dark-bordered cards
-
Subtle bends or indentations only visible under angled light
Tip: Use a magnifying glass or zoomed-in phone photo to check. Even if they look fine at first glance, close-ups often reveal flaws that could knock a grade down from PSA 10 to PSA 8.
🔹 Edges
Clean edges are a sign the card has been stored properly and handled with care. Damaged edges might not be obvious at first glance but can absolutely affect grading.
Look for these imperfections:
- Edge chipping — where the top layer of color flakes off and you see white fuzz
- Mini “nicks” or dents along the side
-
Fraying or lifting of the cardboard layers, especially on older cards
Card Type Watchout: On older Topps and O-Pee-Chee cards (like vintage baseball or hockey), rougher edges can be factory-typical—but still count against you in grading.
🔹 Surface
Surface flaws are often the hardest to spot but can ruin an otherwise perfect card. You’ll want to examine the surface under strong, angled light—natural daylight or a bright LED is best.
Look for these imperfections:
- Scratches or print lines (especially on chrome or foil finishes)
- Surface indentations from handling, stacking, or packaging pressure
- Ink smudges, roller lines, or misprints
- Fingerprints or smudges — common with glossy cards
Tip: Tilt the card slowly under light to catch fine scratches or dents. If you're using your phone, shoot close-up angled photos—you’ll be shocked at what you see.
🔹 Centering
Centering refers to how evenly the image is printed on the card. Poor centering can be the only flaw on an otherwise perfect card—and it still drops the grade.
How to check centering:
- Eyeball the borders — Is the left/right or top/bottom border noticeably uneven?
- Use a centering tool — Print one online or buy a clear acrylic template
The PSA Grading company allows 60/40 centering (left/right or top/bottom) for a PSA 9 Grade and 55/45 or better for a PSA 10 Grade.
🔍 Pro Tips for Evaluating Card Condition
- Use consistent lighting – Natural light or a bright desk lamp works best.
- Compare to PSA 10 images – Use the PSA Pop Report or search eBay sold listings for slab photos.
- Handle with care – Always use clean hands or gloves. A fingerprint on a chrome card can stain permanently.
-
Use a lint-free cloth – To gently remove dust or fingerprints from modern glossy cards.
By learning how to evaluate your cards like a pro, you’ll not only avoid wasted grading fees but also maximize your sale prices by setting proper expectations with buyers. Once you know your card’s true condition, you’re ready for the next step—understanding what it’s worth on today’s market.

2 - Know What You Have — How to Research Card Value
Once you’ve evaluated your card’s condition, it’s time to figure out how much it’s actually worth—and today's value is what matters. Just because someone listed the same card for $1,000 doesn’t mean it ever sold for that.
Whether you’re holding a rookie card of a rising star or a vintage card from your childhood, understanding market value is essential before you grade, list, or trade.
🔍 Step 1: Identify the Card Accurately
Before you can price your card, you need to correctly identify it. There are common and limited identifiers. Figure out the following:
Four main attributes of every card:
- Player Name
- Set Name (e.g., Topps Chrome, Bowman Chrome, Panini Prizm, Upper Deck Series 1)
- Year (e.g., 2022, 1993, etc.)
- Card Number (usually found on the back)
Other attributes that your card might have:
- Is the card a Parallel or Insert? If yes, include the parallel or insert name in search (e.g., Refractor, Green Ice /99, Short Print).
- Is it a rookie card or 1st Bowman? If yes, include term: “rookie” or “1st Bowman” in search.
- Is it an autographed card? If yes, include term: “autograph” in search.
💰 Step 2: Check Real Market Data (Not Just Asking Prices)
The most accurate way to research value is to find recent sales, not current listings. Here's how:
📦 eBay Sold Listings (Check Graphic Below)
- Go to eBay
- Type in your card’s name
- Check the “Sold Items” filter
- Scroll through the most recent results. This shows you what buyers actually paid for the card.
📊 130point.com
A collector favorite. It pulls recent eBay sales data—including accepted best offers—with cleaner formatting than eBay.
📉 Raw vs. Graded Price Research
Be careful not to compare apples to oranges. A raw card (ungraded) will almost always sell for less than a PSA 9 or 10.
Different conditions impact the value of the same card:
So if your card has centering issues or dinged corners, that $75 PSA 10 sale might not apply to your card.
🧠 Bonus Tips for Researching Card Value
- Check Pop Reports – PSA and BGS provide population counts, showing how many of each card exist in each grade. Lower pops = more value (especially in high grades).
- Be Aware – Just because a card once sold for a lot doesn’t mean it still will. Prices fluctuate with player performance, seasonality, and hype.
- Look for Trends – Is the card rising in value, holding steady, or declining?
💡 What to Watch for When Researching
🚫 Common Research Mistakes
- Only looking at current eBay listings (not sold prices)
- Using the highest sale to price your card
- Comparing a raw (ungraded) card to PSA 10 sales without factoring in condition
- Not realizing you may have a base card—not a more valuable parallel, short print, or rare card
Bottom Line:
The more you know about your card’s actual value, the smarter your decisions will be—whether that’s grading it, holding it, or listing it. Once you’re confident in both condition and value, you’re ready to decide: is this card worth grading? We’ll find out below.

3 - Should You Get Your Card Graded?
One of the most common questions sellers ask is: “Should I get this card graded before I sell it?” And the honest answer is: it depends.
Grading can significantly increase the value of certain cards—especially rookies, rare parallels, or vintage gems. But it also costs money, takes time, and isn’t always worth the effort.
This section helps you figure out if grading is a smart move for your specific card.
📦 What Is Card Grading?
Grading is the process of submitting your card to a third-party company that professionally evaluates its condition and assigns it a score (typically from 1 to 10). It then gets sealed in a tamper-proof case with a label that includes the grade and unique serial number.
Note: Bulk submission discounts, insurance, and shipping fees may apply.
✅ When Grading Is Worth It
Grading is often worth it when the potential increase in card value outweighs the cost of grading. Here are scenarios where it makes sense:
💎 You believe the card is in mint or gem mint condition
If your card could score a PSA 9 or 10, grading may double, triple, or even 10x the value.
🎯 The card has strong market demand
Examples: Top rookies (e.g., Jackson Holliday, Connor Bedard), 1st Bowman Chrome cards, low-pop short prints, iconic vintage cards.
💰 You’re targeting serious buyers
High-end buyers want assurance. A slabbed (graded) card signals authenticity, trust, and protection.
🔁 You want to flip or invest long-term
Some collectors slab cards just to hold them for future gains. Grading protects the card and boosts resale flexibility.
❌ When Grading Is NOT Worth It
On the flip side, grading isn’t always a good investment. Here are times to skip it:
🩹 The card has obvious flaws
Off-center? Dinged corners? Surface issues? It likely won’t get above a PSA 7 or 8—and may lose value compared to selling raw.
🔄 The card has low resale value
If the highest graded version of the card’s sales (PSA 10) are under $50, the grading fee might eat your entire profit. This is common with modern base cards or overprinted inserts.
🧊 You need fast cash
Grading takes time. If you need to sell now, consider selling raw—especially for cards in demand.
🃏 It’s a card with uncertain market interest
Some cards look flashy but have no resale market. Research before you invest in grading.
🛠️ Should You Grade It Yourself or Use a Group Submitter?
Grading companies allow individual submissions through their websites, but many collectors use group submitters to save money and get help navigating the process.
🧑🤝🧑 For more on group submissions check with your Local Card Shop.
✍️ Summary: Should You Grade?
Ask yourself:
- Is the card valuable enough to justify the grading cost?
- Is it in strong enough condition to score PSA 9 or 10?
- Would grading significantly boost buyer confidence or resale value?
If the answer is yes to all these questions—grading is probably worth it.
