NTS Sessions warped vinyl

Hi all 

I have all 4 NTS Sessions that are warped when sent form warp records. 

They sent out replacements and I'm thinking of selling the warped vinyl. 

I only considered asking for replacement after reading posts on here. to my ears they sound no different but on some recorded you can see it wobble on the turn table but does bot effect the sound, 

​the sleeves are a paper copies of the originals as sent by warp. 

my question is how much do you think they are worth as I'm thinking of listing on Ebay. 

they will be shipped in the cardboard packaging warp sent. also the nts box will not be included.

thanks
