What is the value of a used game ball signed by robbison cano?

Answer 1

Robinson Cano single signed Game used baseball

A Robinson Cano single signed baseball is worth about $35.-$45. Signatures authenticated in person by a reputable company that uses holograms like Steiner Sports will sell at a higher value.

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.

The game used baseball could lessen the value of the signature based on condition. A clean white baseball would be most preferred for the signature.

The added value of a "game used" baseball will rely on your ability to prove so. Otherwise it will be valued as a used Major League Baseball, and will have a lower value than a baseball that is in clean mint condition. A "Game used" baseball would have to be accompanied with provenance, and the quality of the provenance will dictate the value. A letter from a player, team, or League official would be acceptable. A letter from a fan at the game would not hold much weight if any. Without provenance the added value will rely on the buyers belief in your story.
