A Tommy Lasorda single signed baseball is worth about $60.-$70. Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the signature. Signatures that have not been properly authenticated could sell at half the market value or less. Add for inscriptions. Inscriptions such as a baseball dated "1937" by Tommy Lasorda could add value, as will a vintage 1937 North Carolina State League baseball, but the signature is the centerpiece, and will hold the bulk of the value. In a recent auction (Feb. 2008) a Tommy Lasorda single signed baseball sold for $95.60
