A PSA 10 can make a vintage Pokémon card worth about 2.5 to 13.8 times its PSA 9 value in documented 1999 examples. In dollars, that can add roughly $105 on a first-edition common or more than $62,800 on a shadowless Charizard, according to PSA's 1999 Pokémon Game price guide. A PSA 10 is PSA's Gem Mint grade for a virtually perfect card. The "premium" is the additional amount buyers pay over the same card and printing in a lower grade, usually PSA 9.

How large is the premium on specific cards?
The difference varies dramatically by card. Scarce, desirable holographic cards can gain tens of thousands of dollars, while a common may gain only a little over $100.
PSA's guide provides these comparisons: These figures show why a percentage alone can mislead. A 7× multiplier represents a vastly different financial decision on a $350 card than on a $5,600 card.
- First-edition common: $175 in PSA 10 versus $70 in PSA 9—a $105 or 2.5× difference.
- Shadowless Gyarados: $3,000 versus $350—about $2,650 or 8.6× more.
- Shadowless Blastoise: $15,000 versus $2,000—about $13,000 or 7.5× more.
- First-edition Blastoise: $38,600+ versus $5,600+—at least $33,000 or roughly 6.9× more.
- Shadowless Charizard: $67,700+ versus $4,900—more than $62,800 or about 13.8× more.
Why does one grade add so much?
The jump reflects a demanding condition threshold, not authentication alone. psa's grading standards describe a Gem Mint 10 as virtually perfect, with sharp corners, original gloss, strong focus, no staining, and approximately 55/45-or-better front centering. A PSA 9 can still be an attractive high-grade card.
The premium appears because far fewer submitted copies may satisfy every PSA 10 requirement, especially when buyers are choosing between otherwise identical cards. Shadowless Charizard illustrates that scarcity. PSA CardFacts lists 58 PSA 10 copies and 848 PSA 9 copies, making the recorded PSA 10 population about one-fifteenth as large as the PSA 9 population. PSA also warns that census figures can change or contain errors, so population should inform a price decision rather than determine it by itself.
Should you rely on a price-guide multiplier?
Use guide values as reference points, then examine sales for the exact card. Set, printing, card number, and grade all matter; a multiplier from shadowless Charizard should not be transferred to an unlimited card or a first-edition common. Actual results may also differ from guide values.
PSA CardFacts recorded a shadowless Charizard PSA 10 sale of $54,655 on July 6, 2025, while its PSA 9 grade table showed a $6,300.13 average—an approximately 8.7× comparison. Those figures compare one realized sale with a grade average, not two cards sold together under identical conditions. That distinction matters when a single expensive sale drives expectations. The most useful comparison is a group of recent transactions for the same version and grade, not the largest reported multiplier from another card.
How should you evaluate a PSA 10 purchase?
Calculate both the multiplier and the added dollars. The multiplier shows how aggressively the market rewards the top grade, while the dollar difference shows what choosing PSA 10 actually costs. Before paying the premium: If the available evidence mixes guide estimates, averages, and individual sales, wait for cleaner exact-card comparisons before treating any multiplier as a fair purchase price.
- Confirm the exact set, printing, card number, and grade.
- Compare PSA 10 sales with PSA 9 sales for that same card.
- Check whether the figures are completed sales, averages, or guide values.
- Review the PSA 10 and PSA 9 populations, remembering that census data can change.
- Subtract the PSA 9 value from the PSA 10 value to find the cash premium.
