Quick answer
CardSpicy measures the PSA 10 / PSA 9 gap on Simplified Chinese Pokémon cards from recorded sales rather than from quoted asking prices, because most Chinese listings still trade thin.
PSA 9 and PSA 10 sit one grade apart, and one grade can move a price by more than any set difference. For Simplified Chinese Pokemon cards the gap is quoted constantly and measured rarely, because most Chinese listings still trade thin. This article measures the gap where it actually exists, and shows what the numbers on price sites mean where it does not. Our general reading rules for graded labels live in our grading guide.
The two grades in one paragraph
A PSA 9 is a card with a visible flaw under close inspection: a light scratch on the case-worthy surface, soft corners, or edge wear that stops it from being gem mint. A PSA 10 is gem mint, the grade collectors treat as the definitive copy. Everything else being equal, a PSA 10 is scarcer in population and carries the entire chase premium of the set. The gap between the two grades is therefore one of the strongest signals in the hobby, and also one of the most misread.
How we measured
We pulled the tier prices for thirteen Simplified Chinese set catalogues from our price data source on 4 October 2026, then opened the individual product pages of twelve sample cards and counted the recorded sales in each grade tab. The sales count matters more than the price: a price with no recorded sales behind it is an estimate produced by a model, not a result produced by trades. Only cards with a deep sales list in both the PSA 9 and PSA 10 tabs count as evidence in this article.
Where both grades actually trade: Collect 151
One Chinese set has a deep two-grade market: Collect 151, and within it the four Pikachu Art Rares and the Mew ex Special Art Rare. Each of the five cards below carried thirty or more recorded sales in both grade tabs when we counted on 4 October 2026.
| Card | Rarity | PSA 9 listing | PSA 10 listing | PSA 10 divided by PSA 9 |
|---|---|---|---|---|
| Pikachu #172 | Art Rare | $1,697.66 | $2,794.99 | 1.65x |
| Pikachu #171 | Art Rare | $592.09 | $1,397.53 | 2.36x |
| Pikachu #173 | Art Rare | $891.00 | $1,019.19 | 1.14x |
| Pikachu #170 | Art Rare | $667.00 | $1,055.00 | 1.58x |
| Mew EX #191 | Special Art Rare | $226.60 | $375.00 | 1.65x |
Read the last column with care. The premium ranged from 1.14x to 2.36x, and the median was 1.65x. Two cards with the same rarity and the same set, Pikachu #171 and Pikachu #173, sat at the two ends of that range at the same moment. For one concrete pair: in late September and early October 2026 the same Pikachu #172 sold between $1,475.99 and $1,750.00 as a PSA 9 and between $2,325.00 and $2,750.00 as a PSA 10 in its five most recent recorded trades.
The trap: confident prices with zero sales
Outside Collect 151, the graded tiers of the Chinese line are thin. The 30th Celebration set shows the pattern at its clearest. We sampled four of its cards across the price range, and every one listed a PSA 9 and a PSA 10 price while the recorded sales list in both grade tabs showed zero entries:
Charizard #137: shown PSA 9 $150.62, shown PSA 10 $573.76, recorded sales in either graded tab: 0, while the ungraded tab carried 30 recent trades.
Mewtwo ex #134: shown PSA 9 $49.23, shown PSA 10 $181.68, recorded sales in either graded tab: 0, while the ungraded tab carried 30 recent trades.
Pikachu ex #127: shown PSA 9 $71.67, shown PSA 10 $268.46, recorded sales in either graded tab: 0, while the ungraded tab carried 30 recent trades.
Lapras #106: shown PSA 9 $26.86, shown PSA 10 $95.20, recorded sales in either graded tab: 0, while the ungraded tab carried 12 recent trades.
The whole 30th Celebration catalogue made the same point from above. Across the 104 cards where both graded tiers displayed a price, the implied PSA 10 premium sat inside a narrow band from 3.12x to 3.81x. Real markets do not agree with themselves that tightly across a hundred cards; pricing models do. That narrow corridor is the signature of estimates, and any article or listing that quotes a 30th Celebration grade gap as fact is quoting the model, not the market.
What actually moves the premium
Where the gap is real, three forces drive it. Population: the scarcer the PSA 10 copies relative to PSA 9, the wider the premium, which is why the four Pikachu Art Rares of Collect 151, with their enormous ungraded volumes, still hold a measurable graded gap. Eye appeal: a set whose chase art changes colour dramatically under tilt rewards the gem mint copy more than a set whose art is dark. Timing: premiums compress when a set reprints and stretch when a set goes out of print, so a gap measured in one month is not a permanent fact about the set.
What this means for buyers and sellers
If you buy: on a card with deep grade tabs, decide what the premium is worth to you on the day, because it moves. On a card with empty grade tabs, ignore the displayed premium entirely and price the card from its ungraded trades, which is the only tier with real volume on most Chinese sets. If you sell: a PSA 9 copy of a hot chase is not a discount copy, it is the entry tier that the next collector can actually afford, and the measured gap on Collect 151 shows the market paying from roughly 1.14x upward for the gem mint step.
Where this leaves the Chinese market
Simplified Chinese grading is growing from a thin base, and the honest summary of October 2026 is this: one set, Collect 151, has a grade gap you can measure; the rest of the line has a grade gap you can only estimate. That will change as population reports fill in. Until it does, count sales before you trust a spread.
Frequently asked questions
How much more is a PSA 10 than a PSA 9 on Chinese cards?
On the five Collect 151 cards we verified with deep markets in both grades, the PSA 10 listing sat between 1.14x and 2.36x the PSA 9 listing, and the median was 1.65x. The premium is real but far from uniform, and it is only measurable where both grades actually trade.
Why do price websites show large PSA 10 premiums for cards that never trade?
Aggregators fill missing tiers with model estimates. On every 30th Celebration card we sampled, the PSA 9 and PSA 10 tabs listed confident prices while the recorded sales list showed zero entries, so the displayed premium is a model output, not a market result.
Is a PSA 9 a bad buy?
No. When the PSA 10 premium runs hot, a clean PSA 9 of the same card delivers the same artwork and set identity for a fraction of the price. The gap we measured on Collect 151 means the PSA 9 kept most of the card’s identity value on every card we checked.
How can I check a price gap myself before paying?
Open the card’s product page on the price site and count the recorded sales in each grade tab. If a tier shows fewer sales than you can count on one hand, treat its price as a rough indicator only. Real gaps come from tabs with a deep sales list.
