UNDATED (CBS) - More than 30 years ago, a Florida man began collecting Hollywood and sports memorabilia. His collection is now worth millions. An now he's selling it all in a bid to save his daughter's life.

This auction house in Oakland Park, Florida is crammed with more than 7,000 autographed books, 22,000 autographed photos and 60,000 signed trading cards. Ken Kallin says, "It's a goal that has been accomplished. It's nice to set a goal and finally reach it."

It belongs to 67-year-old Ken Kallin, who didn't start out as a collector but by working in Hollywood that's how he met Bette Davis in 1980. He says, "I did the unpardonable sin and I asked her do you have any photo, anything with your picture on it that you can sign. She had her assistant go into the bureau inside and pull out five old vintage photos and signed all five."

Hollywood didn't work out but over the past three decades, any time a celebrity drew near, Kallin had their photograph and a pen ready to go. He looked for autographed books in thrift stores, making discoveries like this one signed by Nelson Mandela.

His sports memorabilia includes thousands of rare baseball cards virtually all of them signed. This one is the Hall of Fame plaque card of former Yankee great Yoki Berra.

Now it's all going up for auction and experts say the sale might be a record breaker. Scott Grasso says, "I believe that once the books change hands, it'll be the largest personal collection of books, autographed, ever changing hands."

But for Kallin, getting rich isn't his objective. What he hopes to do is help save his daughter's life.

Julie Susi suffers from a rare autoimmune disease, mixed connective tissue disorder, her bones are brittle, several are broken now, and her body is essentially attacking itself. She says, "I want to sleep all day, but I still get up. I have a 17 and a 15-year-old that I'm trying to raise and to be a productive woman. So, I have to be there for them."

As Julie's skyrocketing medical bills mounted, her father decided the best way he could help would be to sell his most prized possessions. Julie wasn't even aware how vast his collection was. Susi says, "I was amazed. I was just mesmerized. I sat there for probably about 30 minutes just looking and looking and saying to myself, wow, my father. This is it. He finally did it."

It's hoped the auction could raise as much as $4.5 million and, in doing so Kallin also hopes to raise awareness about Julie's life-threatening condition, which remains without a cure.
