The value of an autographed Baseball will rely on a number of factors, and the most important is who signed it. A single signed baseball of a less popular player could sell from $10.-$20. A signature from a player that is a fan favorite could sell in the $30.-$40. price range. A noted ballplayer or All-Star could sell in the $30.-$60. price range, and HOF players could sell From $100. -$200 for players like Sandy Kofax or Willie McCovey to $300.-$600 for players like Mickey Mantle and Ted Williams. Legendary players like Babe Ruth, Ty Cobb, or Joe Jackson can sell in the Thousands. Scarcity could factor in on value as well. Old time players that did not sign often, and are hard to find will sell at a higher price. Active ballplayers signatures could command a high value because of the high demand, and fees charged at autograph signings. A player that commonly signs could sell for less. Signatures will vary in price based on condition, the type of authenticity that accompanies the signature, the item signed, and how well the item displays the signature.

Autographed baseball cardsIn general, collectors of baseball cards would rather have a baseball card without the signature. The signature would be considered as a flaw in the condition of the card and will lower the value. If the signature has a lower value than the card it will lower the value of the card. The un-signed card will have a higher value.
