Card grading is not an exact science. Two collectors can look at the same card and still sit one grade apart. On GoSwapCards, the practical rule is simple: grade conservatively, show clear photos, and explain anything a buyer could reasonably dispute later.
Use this guide to compare condition grades, check example photos, and understand fair resolution ranges when a card is listed too high.
Check the back edges first
Back-edge whitening is the most common overgrading mistake. Turn the card over and check all four edges on the back in strong light before you pick a grade — wear that is easy to miss from the front is often obvious from the back.
A clean collector copy with only minor handling signs. Small edge wear or tiny surface marks can still exist, but the card should remain sharp, clean, and attractive overall.
Light visible wear is present, but the card still looks clean in a binder or sleeve. This is often the right grade when the card is no longer Near Mint but still clearly above a played copy.
Clear play wear is visible without the card necessarily being damaged. The card is still intact, but it is no longer a clean collector-grade copy.
Major visible wear is present. The card may still be sleeve-playable or collectible as a budget copy, but strong defects are obvious even at a quick glance.
Structural damage, major moisture damage, peeling, tearing, or tampering is present. When a card is materially changed or compromised, it must be listed as DMG even if other areas still look decent.
Condition mismatch guide
These ranges are practical starting points when the buyer keeps the card. They are not automatic payouts. The right outcome depends on the card, the photos, the listing, and whether both sides agree. A return or GoSwapCards review can still be the better solution for severe damage, wrong cards, hidden alteration, or buyer/seller disagreement.
1 grade lower
Advertised NM, received LP
10–20% partial refund range
Use when the buyer wants to keep the card and the mismatch is clear but limited.
2 grades lower
Advertised NM, received MP
20–30% partial refund range
Use when wear is clearly stronger than advertised, but the card is still acceptable to keep.
3 grades lower
Advertised NM, received HP
30–40% partial refund range
Use when strong wear is obvious and the buyer still prefers keeping the card.
4 grades lower
Advertised NM, received DMG
40–50% partial refund range
Use only if the buyer still wants to keep the damaged card. Return may be more appropriate.
Severe hidden damage
Undisclosed crease, water damage, alteration, or structural damage
50–60% review range
GoSwapCards may require a return or admin review instead of a partial refund.
If a card sits between two grades, use the lower grade. Buyers accept conservative grading much more easily than optimistic grading.
Condition is based on the real card, not on intention. A clean front with a damaged back is still graded by the worst meaningful defect, not by the best angle.
If a defect could change a buying decision, it should be visible in the photos and mentioned in the description. This is especially important for bends, dents, foil scratches, clouding, stains, signatures, restoration, and edge wear.
When a card has material alteration or structural damage, it should be treated as the worst relevant condition rather than as a nicer grade with a footnote.
If a card has been trimmed, recolored, inked, glued, cleaned aggressively, or otherwise materially altered, list it conservatively. If the alteration changes the card itself rather than just its appearance in a minor way, the safe default is DMG and clear disclosure.
A signature must always be disclosed. Do not hide it inside a normal NM, LP, or MP listing without explanation. If the signature is unofficial or affects desirability for most buyers, use conservative grading and clear photos.
Water exposure, swelling, rippling, stains, peeling, or fiber damage should generally be treated as DMG. Even if the card still looks acceptable from one angle, the underlying damage matters.
Vintage cards can still be NM if they are truly clean. Age alone does not lower the condition, but age-related wear does. Grade the actual card in front of you, not the era it comes from.
If you list a graded card, show the slab clearly and do not convert the slab grade into a different raw condition without explanation. If you list a card as raw, grade it using the GoSwapCards labels, not a guessed PSA equivalent.
Do not invent extra condition steps if the app uses NM, LP, MP, HP, and DMG. Choose the closest real option and explain the defect in the description if the card sits between two grades.
