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.

Collectors will pay more for inscriptions like "The Man" or "HOF 69", and pay less for personal inscriptions like "Good Luck Chuck" If your baseball is inscribed "1963" by Musial you could add value.
