The Mets on Monday put the current Shea Stadium seats on sale via their Website, and they’ve been selling like hotcakes. According to a report in amNew York on Tuesday, the team has sold over 6000 seats at $869 a pair. David Freedlander writes that the Yanks will soon start putting parts of the old stadium on sale, but final details have yet to be worked out. You can bet that the cost for parts will be much higher than Shea, an ugly and relatively unpopular stadium with far less historical significance than Yankee Stadium.
