CAMDEN, N.J. -- Kobe Bryant is in a court battle to try to keep his mother from auctioning off mementos from his high school days in Pennsylvania and his early years with the Los Angeles Lakers.

A New Jersey auction house filed a lawsuit in U.S. District Court in Camden on Thursday for the right to sell the stuff after the NBA star's lawyers wrote the firm telling it to cancel a planned June auction.

The disagreement is a high-value, high-profile version of a question many families face: Can Mom get rid of the stuff a grown child left at home?

Pamela Bryant intends to sell: the NBA star's jerseys, practice gear and sweatsuits from Lower Merion High School; varsity letters; a trophy for being the outstanding player at the 1995 Adidas ABCD basketball camp; and a signed basketball from the 2000 NBA championship game.

And then there are rings, for the 1996 Pennsylvania high school championship, a pair that the Lakers made for Bryant's parents for the 2000 NBA championship and one from the 1998 NBA All-Star Game.

According to court filings, Pamela Bryant struck a deal in January with Goldin Auctions in Berlin, N.J., which earlier this year sold a rare Honus Wagner baseball card for a record $2.1 million.

She got $450,000 up front, which she intended to use for a new home in Nevada.

A source told ESPN that Kobe Bryant offered to pay his mother up $250,000 toward a home she wanted.

She refused, saying she wanted $450,000. When Kobe Bryant turned her down, the source said that unbeknownst to Kobe Bryant she struck a deal to get the $450,000 advanced through the auction company.

The source said Kobe Bryant was unaware that his memorabilia was being auctioned until hours before the auction company released the news of the sale.
