Story highlights Arthur Ashe died of AIDS at the age of 49 in 1993

He was the first black man to win the U.S. Open and Wimbledon

The items up for auction are valued between $200,000 and $600,000

A portion of the proceeds will benefit the Arthur Ashe Learning Center

The largest collection ever of Arthur Ashe memorabilia will be auctioned off next week on the 20th anniversary of the tennis legend's death, with everything from his trophies to his wisdom teeth up for grabs.

A portion of the proceeds from the sale by the Ashe family will go to the Arthur Ashe Learning Center , the non-profit foundation that promotes the tennis great's legacy as an athlete and activist.

"Arthur Ashe's life and career is really about the highest highs and lowest lows," said Nate D. Sanders, who will hold the online auction on February 6.

Ashe was the first black man to win the U.S. Open in 1968 and Wimbledon in 1975, and become known in later years for promoting racial tolerance and AIDS awareness.

Tennis player Arthur Ashe was a prominent African American tennis player. During his playing career, he won three Grand Slam titles.

Ashe was forced to disclose he had AIDS in 1992 after being told that USA Today intended to print a story about his illness as soon as it could confirm it.

In a televised news conference, Ashe told the world he contracted AIDS through a tainted blood transfusion during heart-bypass surgery in the 1980s.

"I am sorry I have been forced to make this revelation now at this time," he said at the time. "After all, I am not running for some office of public trust nor do I have stockholders to account to. It is only that I only fall under the dubious umbrella of 'public figure.'"

He died at the age of 49 on February 6, 1993.
