Is my card worth grading? A centering-first checklist
Centering Lab · Published and updated:
A card may be worth grading for preservation, authentication or a collection goal, but centering alone cannot answer the whole question. Start by measuring both faces: a clear front result beyond the current PSA 10 reference of approximately 55/45, or a reverse beyond 75/25, removes that centering ceiling in the model before corners, edges and surface are considered. Then compare your actual submission costs with relevant card values and the purpose of the holder, without assuming the highest grade.
What should you decide before inspecting the card?
Write down why you want it graded. Completing a labelled set, protecting a sentimental copy, checking authenticity and preparing a possible sale are different goals. For a personal collection, the usefulness of a holder can matter even if the submitted card is unlikely to cover its costs. For a possible sale, a large advertised price for a top-grade copy is not enough evidence about your own ungraded card.
Identify the exact card first: set, number, language, printing, finish and any edition distinction. A comparison with a different variant can make even a careful condition review irrelevant. Keep a short record of the photographs and visible defects so your submission decision is based on the same copy throughout, not a better-looking example found later.
How does a centering-first screen save unnecessary work?
Measure a complete, straight front photo and a separate reverse photo. Confirm the physical cut and printed frame before trusting a ratio. Record both axes, uncertainty and warnings, then compare with the chosen house's band. If your goal specifically requires a top label and the measurement clearly excludes that centering band, you can pause before spending more time on an exhaustive inspection.
| House and grade | Front: worse axis | Front: other axis | Back | Status (front / back) |
|---|---|---|---|---|
| PSA 10 GEM MT | 55/45 | 55/45 | 75/25 | official / official |
| BGS 9.5 Gem Mint | 55/45 | 52/48 | 60/40 | interpreted / interpreted |
| CGC 10 Gem Mint | 55/45 | 55/45 | 75/25 | official / interpreted |
| SGC 10 Gem Mint | 55/45 | 55/45 | — | approximate / — |
Limits apply to both axes separately. For BGS front, the worse axis must meet the loose limit and the other axis the tight limit. — means no separate numerical back rule in this model. A ceiling is not an overall grade.
This screen is asymmetric: a clear failure can exclude a model band, while a pass cannot prove the final grade. Uncertain boundaries do not justify calling a failure; improve the evidence first. For SGC, the missing numerical reverse rule leaves an incomplete screen. For Pristine, the model's perfect-centering convention is interpreted. The house comparison gives the caveats needed to use the table honestly.
When does centering alone exclude the top model band?
Example one: opposite front borders measure 3.60 and 2.40 mm. The sum is 6.00 mm; 3.60 ÷ 6.00 × 100 = 60%, or 60/40. With the other front axis equal, the PSA front ceiling is 9 MINT. If independent clear captures support that result and its uncertainty does not cross the boundary, the model excludes PSA's top centering band regardless of how clean the corners look.
Example two: the front is 50/50 on both axes, but one reverse pair measures 6.40 and 1.60 mm. That gives 6.40 ÷ 8.00 × 100 = 80%, or 80/20, with the other reverse axis equal. The PSA back ceiling is 9 MINT and limits the combined result. A centred front cannot rescue it.
Do not use these examples as verdicts from a casual seller thumbnail. Border choice, perspective and rounding matter near a limit. The ratio guide explains the arithmetic, and the front/back guide explains the combination. Neither provides a probability of receiving a particular final grade.
What comes after centering in the inspection checklist?
Inspect all four corners on both faces for whitening, wear, bends or deformation. Rounded factory geometry and actual damage should not be conflated, but a photo may not resolve the distinction. Use good light and magnification where useful, without pretending that one photo reproduces a grading room's examination.
Check the physical edges for chips, rough patches, whitening or evidence of alteration. The printed-border width measured for centering is a different property from edge condition. Do not “correct” a centering problem by trimming a card; PSA's standards address tampering, and alteration can change whether a card is eligible for a normal grade.
Inspect the surface under changing light for scratches, dents, creases, print lines, stains and loss of finish. Some defects are visible only when the reflection changes. A fresh pack opening does not prove flawless condition. Record each concern rather than trying to convert it into a guessed numerical penalty; Centering Lab does not model those penalties.
How should tilted printing and a possible miscut change the decision?
A tilted printed frame produces borders that narrow and widen along their length. A single central reading can conceal that geometry. Take a straight photograph, check several positions and keep the tilt warning. Perspective correction should rectify the card plane while preserving real print tilt.
The CGC error guide distinguishes specific cutting errors. A very narrow or missing margin may indicate severe displacement or a possible miscut, but a ratio alone does not classify a collectible error. An alignment mark, cut-off design or part of another card is relevant evidence for a specialist to examine. Contact the chosen service about the exact issue and available designation before submitting. Do not assume an unusual cut automatically increases desirability or value, and do not force an absent border into an ordinary centering measurement.
How do you compare grading cost with the card's value?
Obtain a current quote from the service you would actually use. Check grading fee, shipping both ways, insurance, tax, any membership or intermediary charge and the applicable declared-value terms. Use the service's current pages, such as PSA submission services and CGC fees, rather than a price copied from an old article.
For a sale-oriented decision, use completed transactions for the exact variant and clearly identified grades, with relevant fees and shipping accounted for. Asking prices are not completed sales. Keep the ungraded comparison and plausible lower-grade outcomes in view. If the case only works with the maximum grade, the centering pass does not make that outcome reliable. Where transactions are sparse or condition cannot be assessed, mark the value comparison as uncertain.
You can express the comparison without inventing prices: total submission cost versus the difference between comparable net graded and ungraded sale proceeds. That is a scenario check, not a promised return or a personal recommendation. For a collection goal, decide separately how much the holder's practical or sentimental purpose matters to you. The measurement method and full standards describe exactly what this checker can contribute to that decision.
Frequently asked questions
Does a centering pass give a probability of getting the maximum grade?
No. It keeps a centering band available under the model. The tool does not assess all other condition criteria or provide a calibrated probability for the final grade.
Is a pack-fresh card necessarily ready for a top-grade submission?
No. Manufacturing, cutting and handling can leave defects before the card reaches your collection. Inspect the specific copy, including its reverse, instead of relying on how it was acquired.
Should I assume a possible miscut will be worth more in a holder?
No. Classification, service eligibility and collector interest require separate evidence. Ask about the exact error and compare relevant completed transactions if value matters to your decision.
What if there are too few comparable completed sales?
Treat the value comparison as uncertain. Do not replace missing evidence with a top-grade asking price. A personal collection goal can still justify a submission for reasons you choose explicitly.
