It depends entirely on the card, but the jump can be dramatic. For desirable modern cards, a 10 often sells for two to several times the price of a 9, because so few copies achieve the top grade. For common or lower-demand cards, the gap may be small. The premium is driven by scarcity at the top: if a card is easy to pull in Gem Mint, the 10 premium shrinks; if 10s are rare, it balloons. Always check recent sold "comps" for both grades of your exact card before assuming a number. This gap is also why centering and surface flaws matter so much — they're what knocks a 10 down to a 9.
