Should You Grade Your Card?

Grading is an investment of time and money. Use this guide to decide if it makes sense for your card.

Grade Your Card If…

  • It features a star player or iconic character (Jordan, Mantle, Charizard, Brady)
  • Condition appears Near Mint (NM) or better — sharp corners, clean surface, strong centering
  • Raw value is $75–$100 or higher, giving grading fees room to make sense financially
  • A PSA 9 or PSA 10 would multiply the value by 3× or more based on recent sales comps
  • You plan to hold long-term and want third-party authentication and encapsulation protection
  • The card has a low PSA 10 population — meaning fewer graded copies means higher scarcity premium

Skip Grading If…

  • It's a common player or low-demand card where PSA 10 copies sell for under $50
  • Visible wear is present — rounded corners, creases, surface scratches — grading would just confirm the damage
  • The raw value is under $30 and grading fees ($25–$150) would exceed any potential grade premium
  • You need quick cash — grading turnarounds range from weeks to months, locking up your inventory
  • The card has a massive PSA 10 population, making any graded copy just another in a sea of them
  • It's a reprint, promo, or modern parallel with limited collector demand in slabbed form

The 4 Pillars: How Graders Evaluate Cards

PSA, BGS, and CGC all evaluate the same four criteria. Understanding each is essential before any submission.

01
Centering
PSA 10: 55/45 front · 65/35 back

Centering measures how evenly the printed image is positioned within the card's borders. PSA requires the front borders to be no worse than 55/45 (left-to-right and top-to-bottom) and 65/35 on the back for a PSA 10. Use calipers or a centering tool to measure at home before submitting — centering is often the dealbreaker.

02
Corners
Look at 45° under bright light

Corners are graded under magnification. Sharp, needle-point corners with no fraying or wear indicate a PSA 10 candidate. Even a single fuzzy or dinged corner can drop a card to PSA 8 or lower. Inspect all four corners under a bright directional light source, tilting the card to reveal wear invisible in flat lighting.

03
Edges
Feel for chips and roughness

Run your fingertip gently along all four edges of the card. Any chips, dents, nicks, or rough texture will result in edge deductions. White spots on colored-border cards are especially problematic. Edge damage is common from cards stored in binders or sliding against other cards without proper sleeves.

04
Surface
Hardest to detect at home

Surface is the most difficult criterion to evaluate without professional tools. Scratches, print lines, staining, and fingerprint oils all affect the surface score. To inspect, hold the card under a bright lamp (not overhead fluorescent) and rotate it slowly at various angles — surface defects only become visible at specific light angles.

10 Card Grading Tips for 2026

Follow these tips before every submission to maximize your PSA 10 rate and protect your investment.

1
Assess Cards in the Right Lighting

Tilt the card under a bright, focused lamp — not overhead fluorescent lighting — at multiple angles. Surface scratches and print lines only appear at certain light angles and will be completely invisible under flat ambient lighting. The majority of "surprise PSA 8" outcomes happen because collectors assessed their cards in poor lighting conditions at home. A simple desk lamp aimed at a 30–45° angle can reveal flaws that would otherwise only be discovered by a PSA grader. Take your time and rotate the card through a full range of angles, inspecting both front and back thoroughly before committing to a submission fee.

2
Use a Grading Loupe or Jeweler's Loupe

A 10× jeweler's loupe, available for around $15 on Amazon, will reveal corner wear, edge chips, and surface print lines that are completely invisible to the naked eye. This is an essential tool for any serious submitter — PSA graders use magnification and high-powered lights as standard procedure. If you wouldn't submit a diamond for appraisal without knowing its characteristics, don't submit a valuable card without proper inspection tools. A loupe pays for itself the first time it saves you a $50 submission fee on a card that was always going to grade PSA 7.

3
Never Touch the Card Surface with Bare Hands

Fingerprint oils cause surface damage that PSA grades down — oils are acidic and can leave invisible marks that become visible under professional inspection equipment. Always handle cards by the edges only, never touching the front or back of the card. For high-value submissions ($500+), wear lint-free cotton gloves. This also applies when showing cards to friends or potential buyers. A single bare-hand touch to the surface of a pristine vintage card can be the difference between a PSA 10 and a PSA 9 — a gap that on a key card could mean thousands of dollars in lost value.

4
Store in the Right Sleeves Before Submitting

A penny sleeve alone provides minimal protection. The correct storage stack for submission-bound cards is: penny sleeve → semi-rigid card saver (not a hard toploader, which can damage corners) → team bag for transport. PSA accepts cards submitted in penny sleeves or card savers — check their current submission guidelines before mailing, as requirements do update. Hard toploaders can actually damage corners during shipping if the card shifts inside. Semi-rigid card savers provide snug, protective storage without the corner-damage risk of a loose toploader.

5
⚠️ Warning
Don't Clean Your Card — Ever

Attempting to clean a card — even with a soft microfiber cloth — almost always causes additional surface damage. Micro-scratches from wiping, residue from cleaners, and altered surface texture are all detectable by PSA graders under magnification. Never use water, alcohol, cleaning solutions, erasers, or any abrasive material on a card surface. The only minimally safer option is a very gentle breath from a distance followed by a lens air blower for loose dust — and even this carries meaningful risk. If your card is dirty or dusty, that condition should factor into your submission decision, not your cleaning routine.

6
Measure Centering Before Submitting

Purchase a card centering tool or digital calipers ($10–$20) and measure the borders before every submission. Measure the left and right border widths on the front of the card and divide the larger by the smaller to get the centering ratio. Repeat for top and bottom, then again on the card back. Front centering must be within 55/45 for PSA 10 consideration; back centering must be within 65/35. If a card is outside these thresholds, it is capped at PSA 9 at best regardless of perfect corners, edges, and surface. This single step will save you significant submission fees on out-of-spec cards.

7
Research the PSA Pop Report Before Submitting

PSA's Population Report — available at psacard.com — shows how many copies of every card have been graded and at what grade. Before submitting, look up your specific card and check the PSA 10 population. A card with 12 PSA 10 copies carries massive scarcity premium; a card with 4,000 PSA 10 copies has a much smaller grading ROI. High population = lower per-slab premium. Low population = strong PSA 10 upside. Also use the pop report to identify which print runs or variations of a card grade well vs. poorly, informing your raw card buying strategy at shows or on eBay.

8
Choose the Right Grading Service

Not all grading companies are created equal in terms of market recognition and buyer preference. PSA offers the best brand recognition and resale premium across all card categories — for most sellers, PSA is the safe default. BGS (Beckett Grading) is the strictest grader and a BGS 10 Black Label is an extreme rarity that commands enormous premiums, particularly for basketball. CGC is growing rapidly and is strong for Pokémon cards and comics. SGC offers competitive turnaround for vintage baseball. Match your card's category to the service with the strongest buyer community for that type of card.

9
Use Bubble Mailers with Rigid Backing

For shipping submissions, sandwich each sleeved card between two identical-size pieces of corrugated cardboard (cut from a shipping box), tape the sandwich together firmly, and seal in a bubble mailer. The cardboard prevents the card from flexing during transit — a single hard bend can ruin corner sharpness. For submissions of $500+ per card, use a rigid flat-rate box with additional foam padding around the cardboard sandwich. Never send cards in a standard envelope with no rigid backing — mail handling equipment will bend them. Label the package "DO NOT BEND" on all sides.

10
Time Your Submission with Expected Turnaround

PSA turnaround time varies dramatically by service tier: Economy ($25/card) targets approximately 2–6 months; Standard ($50/card) targets 45 business days; Express ($150/card) targets 5 business days. Submitting before a seasonal peak — NFL/NBA playoffs, major Pokémon set releases, a player's playoff run — can affect how quickly your returned slabs capitalize on heightened market demand. Factor turnaround time into your selling window. A card submitted in October for an NFL playoff run might return in January, perfectly timed for Super Bowl season demand spikes.

Frequently Asked Questions

Answers to the most common questions collectors have before their first submission.

A card is generally worth grading if it features a star player or popular character, is in Near Mint (NM) or better condition, and has a raw value of $75–$100 or more where a PSA 9 or PSA 10 would multiply its value by 2–3× or more. Also consider your purpose: long-term holding and authentication are great reasons to grade even cards slightly below the $100 threshold. Use CardValueFinder's free pre-check tool to get an AI-assisted condition estimate before committing to submission fees — it only takes a photo and 30 seconds.
Centering is the single most common reason a card fails to achieve a PSA 10. PSA requires front centering to be no worse than 55/45 left-to-right and top-to-bottom, and 65/35 on the back. Even a card with perfect corners, edges, and surface will be capped at PSA 9 if centering is out of spec. Surface scratches are the second most common issue — many are invisible without a bright directional light or loupe, so proper inspection before submission is absolutely critical to protecting your investment.
No. Attempting to clean a card almost always causes additional surface damage and can result in a lower grade than the card would have received uncleaned. PSA graders are trained to detect cleaning attempts including micro-scratches from cloths, residue from cleaners, and altered surface texture. Never use water, alcohol, cleaning solutions, or any abrasive material on a card. If there is visible dust, a very gentle breath from a distance followed by a lens air blower is the safest possible option — and even that carries meaningful risk on valuable cards.
To measure centering, use digital calipers or a dedicated card centering tool (both available for under $20 online). Measure the border width on the left side and right side of the card front; do the same for top and bottom. Divide the larger measurement by the smaller to get the centering ratio. For example, a left border of 2.2mm and right border of 1.8mm equals 55/45 centering — exactly at the PSA 10 threshold. Any ratio worse than 55/45 front or 65/35 back disqualifies the card from PSA 10 consideration, period.
A PSA 9 (Mint) allows for one minor centering imperfection, one minor print dot, or very slight wear on one or two corners — but still must appear nearly perfect to the naked eye. A PSA 10 (Gem Mint) requires all four criteria — centering, corners, edges, and surface — to meet the strictest standards with no detectable flaws under normal lighting. In terms of market value, the difference can be enormous: for key rookie cards, a PSA 10 is often worth 3–10× more than the same card in PSA 9.
PSA offers multiple service tiers. Economy service ($25/card) targets approximately 2–6 months and requires declared card values under $499. Standard service ($50/card) aims for 45 business days. Express service ($150/card) targets 5 business days. Walk-Through service ($600+/card) offers 2-day turnaround. Actual times vary based on current submission volume. Always check PSA's website for current estimated turnaround times, as they fluctuate seasonally and during high-demand periods following major sports events or set releases.
The PSA Population Report (pop report) is a publicly available database at psacard.com that shows exactly how many copies of each card have been graded and at what grade. It matters enormously for valuation: a card with only 12 PSA 10 copies commands a massive premium over one with 5,000 PSA 10s. Before submitting, always check the pop report to understand the supply of high-grade copies. A card with a very high PSA 10 population may not see its value increase meaningfully after grading, significantly reducing your return on the submission investment.
It depends on your strategy. Buying already-graded cards provides authentication and a third-party condition guarantee, reducing risk — but you pay a premium. Buying raw cards and grading them yourself can yield significant profit if you can accurately assess condition and the card grades PSA 10. This "raw to graded" arbitrage strategy requires skill and experience. For beginners, purchasing already-graded key cards is safer. For experienced collectors, buying underpriced raw cards and submitting is where significant value gets created — especially in less-watched set releases or the vintage market where condition knowledge creates edge.
