Game-used means exactly what it sounds like — a piece of memorabilia that was actually used in a professional sporting event. We're talking bats, jerseys, fielding gloves, batting gloves, bases, and more. The real deal.
In baseball, game-used memorabilia is typically MLB authenticated, meaning Major League Baseball itself guarantees the authenticity and provenance of the item. That authentication adds serious credibility and value.
You'll frequently see game-used pieces embedded in relic cards, though it's worth noting that not all relic cards contain game-used memorabilia — some use event-worn or player-worn items instead. Always check the fine print.
