PSA 10 cards usually sell for a premium over their PSA 9 counterparts because they meet a stricter condition standard, but the size of that premium varies widely by card, set, print run and collector demand. This calculator lets you compare the current PSA 9 and PSA 10 market estimates for a specific card, along with the ungraded value, the dollar spread and the PSA 10 premium. Use it to see, at a glance, how much more a PSA 10 commands over a PSA 9 for the exact card you care about.
Search for a card by name, year, set, player or character, and card number, then pick the exact card from the results. The tool shows the ungraded, PSA 9 and PSA 10 market estimates side by side, plus the dollar spread between PSA 9 and PSA 10, the PSA 10 premium as a percentage, and the PSA 10 price multiple.
Every result has a shareable link so you can send a specific comparison to someone else or come back to it later.
A PSA 9 (Mint) describes a card that is very sharp but has one or more minor flaws — a slightly off-center image, a small edge or corner imperfection, or a tiny surface mark. A PSA 10 (Gem Mint) meets a stricter standard across centering, corners, edges and surface.
Because a PSA 10 clears a higher bar and is scarcer for most cards, it typically carries a higher market value than the same card in PSA 9. The gap between the two is what this calculator measures.
The dollar spread is the PSA 10 value minus the PSA 9 value. The PSA 10 premium percentage is that spread divided by the PSA 9 value, times 100 — how much more, in percent, the PSA 10 commands over PSA 9. The PSA 10 multiple is the PSA 10 value divided by the PSA 9 value.
When either the PSA 9 or PSA 10 value is missing or zero, the tool shows "Insufficient pricing data" instead of a percentage, because those figures would be meaningless or undefined.
Premiums tend to be largest where high-grade copies are genuinely scarce and demand is strong: older cards, cards from sets that are hard to grade well (heavy print lines, centering issues), and cards of players or characters with a large collector base.
Modern, easy-to-grade cards with plentiful PSA 10 supply usually show a smaller premium, because a top grade is common rather than rare.
If the premium for a card is large and you mainly want the card for your collection rather than the top grade, a PSA 9 copy can cost far less while looking very similar to the eye. The calculator's spread and multiple make that trade-off explicit for the specific card you are looking at.
This is a comparison of current market estimates, not advice on what to buy — the right choice depends on your own goals and budget.
These are estimated market values, not guaranteed sale prices. Thinly traded cards can have noisy or stale estimates, and a single unusual sale can move a figure. Values change over time, and the estimate for a grade can be missing when there is too little data.
The tool does not predict what grade a raw card would receive, and it does not include grading fees or sold-comparable evidence.
Values come from PriceCharting and reflect current market estimates for each grade — ungraded, PSA 9 and PSA 10.
They are estimates rather than sold comparables or predictions. We refresh them on a daily cycle and show the date each card was last updated so you can judge how current they are.
A PSA 9 (Mint) is a very sharp card with one or more minor flaws, such as slightly off-center printing or a small edge or surface imperfection. A PSA 10 (Gem Mint) meets a stricter standard across centering, corners, edges and surface, which is why it is scarcer and usually worth more.
It depends entirely on the card. For some cards a PSA 10 is worth a little more than a PSA 9; for others it is several times the price. Use the calculator to see the current dollar spread, premium percentage and multiple for a specific card.
A PSA 9 can be an appealing way to own a card at a lower price than a PSA 10, especially where the PSA 10 premium is large. Whether it is right for you depends on your goals and budget — this tool compares values, it does not give buying advice.
The biggest premiums show up when high-grade copies are genuinely rare and demand is strong — typically older cards, hard-to-grade sets, and cards of popular players or characters.
No. It compares current market values for cards already graded PSA 9 and PSA 10. It does not estimate the odds that a raw card would receive any particular grade.
