Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the baseball. Signatures that have not been properly authenticated could sell at half the market value or less.
Added value of a George Brett "300th home run" baseballwill rely on your ability to prove so. Otherwise it will be valued as a used Major League Baseball, and will have a lower value based on condition. A clean white baseball would be most preferred to display the signature.. A "Game used" baseball would have to be accompanied with provenance, and the quality of the provenance will dictate the value. A letter from a player, team, or League official would be acceptable. A letter from a fan at the game would not hold much weight if any. Without provenance the added value will rely on the buyers belief in your story.
