W:Gruul&Golgari Prerelease Guild Card H:Dimir,Azorious,boros,tradelist

I want to round out my collection Prerelease guild cards, just needing the Gruul and Golgari ones. I have one each of the Dimir, Azorious and Boros cards. Not really sure how to value them (how does $1 sound?) send me a trade!
Thanks
