5,400 exact global searches with 480 local for me. Id say has some value to it developed as the competition is low with this one as well. I would develop it if I owned it as the cost per click average is $3.00 and to me displaying some relevant content could make this one a nice little money maker. Definitely has the potential with some work to do well.
Did you plan on developing this one or selling the domain to the highest bidder? Because there are plenty of images and content available to write about BT Cotton for a website for this domain. Id guess based on rev stats if ranked page one it could possibly pull it could go XX to XXX or more for this one. Only way to tell is monetize it and get some stats to back it up. Unless you find an end user for the term.
