Condition is one of the biggest value drivers in the hobby, and grading turns condition into a standardized number buyers trust. The same card can be worth a few dollars in a low grade and many times that in Gem Mint, because top-grade copies are scarce and command premiums. Each step up the scale generally raises value, with the largest jump usually at the very top (the 9-to-10 leap). Grading also adds a baseline of authenticity and protection that supports price. That said, the premium varies by card and demand — always check recent sold comps for your exact card at each grade. For the mechanics of grades, see our grading FAQs.
