GUEST: It's my father. He was born in Italy, but came here at the turn of the century and just fell in love with baseball.

APPRAISER: Your father was quite ill at the end of his life. This is a personal letter from Lou Gehrig saying he is sorry about your father's illness, and to have a signed letter from him is quite unusual and would sell for about $6,000 to $8,000. The condition of the Goose Gosling ball is appalling.

GUEST: Right.

APPRAISER: That ball is going to be worth about $300 to $400. And these other two balls, which have great signatures, are probably going to be worth about $1,000 to $1,500 each. This Joe DiMaggio letter is worth about $1,000 to $1,500. So this whole wonderful collection together would be valued at about $15,000 to $20,000.

GUEST: I'm overwhelmed!
