NEW YORK --- As a season-ticket holder, Darrell Buono spent 13 years rooting for the New York Mets in blue, loge-level seats at Shea Stadium. So he bought them.

The seats cost $869 a pair and will have a place of honor in Buono's basement when they are shipped, sometime after the final game is played at Shea this fall and the Mets begin dismantling the stadium.

"My wife kind of gave me a strange look when I told her I was doing it," Buono admitted. "But she was OK with it."

The Mets and the Yankees are finishing their final season in their current stadium and will open 2009 in new ballparks. Before they move in to their new homes, memorabilia buffs expect them to strip down the ballparks and auction off anything that will sell.

The Yankees say there will be a sale but haven't released the details yet, and so far the Mets have only put seats on the market. But some think that everything from lockers to strips of sod might go on the market.

New York City will reap the bulk of the profits, because it owns the ballparks.

"This is a cash grab," said Richard Aurigemma, a collector who owns more than 100 seats from different stadiums and also sells ballpark seats through a Web site. "They'll sell anything and everything."

The $869 price tag for Mets seats is a reference to the two years the team won the World Series, 1986 and 1969. Yankees seats will no doubt be pricier, said Aurigemma, who suggested $1,923 a pair to celebrate the year Yankee Stadium opened.

Other teams with new stadiums have held memorabilia sales in recent years. Tiger Stadium seats in Detroit sold for $279 a pair last year. St. Louis Cardinals fans spent a total of nearly $1 million in 2005 to buy pieces of Busch Stadium after it closed, including the locker used by star slugger Albert Pujols (about $20,000) and a clubhouse urinal for more than $2,000.

The Mets put 16,000 pairs of seats up for sale on the team's Web site Aug. 25 after a presale for season-ticket holders.

Under the deal between the city and the Mets, the city gets 70 percent of the profits from Shea Stadium, with the team donating its 30 percent to charity. The Yankees and the city are negotiating how to divide profits from the House that Ruth Built.
