The value of a signed Baseball will rely on who signed the baseball, condition of both the baseball and signature, and the type of authenticity that accompanies it. Signatures that are not properly authenticated could sell at half the markey value or less. If the number of collectors are higher than the number os baseballs in the market it will have a higher value. If the player signs often and the demand is low it will have a lower value.
