How much is a ken grifey jr rookie autograph baseball worth?

Answer 1

A Ken Griffey, Jr. single signed Baseball is worth between $75.-$100.

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 baseball would only be worth more as a "rookie autograph" if Ken Griffey Jr. inscribed the date or "rookie"on the ball. A letter of authenticity dated to Griffey's rookie year might add value. Personal inscription like "Good Luck Charlie" will sell for less. In a recent auction a Ken Griffey, Jr single signed baseball sold for $107.
