With the future of the Astrodome still up in the air, more memorabilia could soon be hitting the auction block.

NRG Park officials said there are at least 4,000 more seats remaining in good condition and they could be available for fans to take home, if the county decides to put them up for sale.

Thousands of people waited in line for hours last November just to get a chance to buy seats and other items. More than $1.5 million was made last year selling memorabilia from the beloved Dome.
