Bobby Bonilla single signed baseball

A Bobby Bonilla single signed baseball is worth about $20.-$30.

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.
