That book reports that Mantle's estate was valued at $8 million to $12 million dollars. His family sued to stop the publication of that book and from discussing Mantle's finances publicly. But a judge ruled against them and they had to pay $3 million in legal fees before they could stop the book from being released.

The value of any sports item, including autographs, increases as the game or event grows more popular and the demand for it rises. Items from players who are active or former professionals are most likely to be collected by fans. Sports items from people who have died are also valuable and can be acquired by their family members.
An autograph's value depends on several factors such as the player's career record, the rarity of his or her signature, and its condition. For example, a signed baseball that has been kept in a safe-deposit box or a vault is worth more than one that has been exposed to sunlight or air-conditioning.
Autographs are usually issued with a label that specifies where and when it was signed. If an item lacks a label, it should be assumed that it was signed in the player's hometown during his career with the major league team.
A signature that appears on a ball that has been autographed by everyone who took part in a drill or practice session is called a "showcase" signature and is worth the most money.
