How much is an autograph book with Pete Rose Frank and Brooks Robinson Jim Bouton Al Downing and others worth?

Answer 1

Autograph Book - Cut Signature Value

A signature in an autograph book would be valued as a "cut signature" and each signature in the book would be valued on it's own merit. Condition of both the paper and signature is important as well as the type of authenticity that accompanies each signature. Signatures that are not properly authenticated could sell at half the market value or less.

A Cut Signature is a signature on a small piece of paper, or "cut" from a larger piece. Cut Signatures are often cut from an item that has been ruined to save its value such as a cover of a publication, photograph, letter or notebook on which it was originally signed. Cuts are commonly used for inserts by Baseball card companies and sell for about 10-20% the price of a signed baseball. Percentage will vary based on the popularity of the player, and the rarity of the signature.

The value for the cut signatures of the players you listed are probably worth about $5.-$15. each.(or less)
