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. Add for inscriptions.
If the baseball was "picked up" off the field as a batting practice ball it could have a lower value based on condition. A clean white baseball would be most preferred to display the siganute.
Collectors will pay more for inscriptions like "406"or "HOF", and pay less for personal inscriptions like "Good Luck Chuck"
