FIFA 14: Ultimate Team coins.

I recently took up Ultimate Team to pass the time, I went the first 6 seasons unbeaten and won the title every time. then, I became pretty sh*t all of a sudden. It was then that I realised (when it comes to FIFA) I may have a bit of an anger issue. long story short, I'm in the process of selling everything I own, is there actually a market for people who wants to buy coins? And what is the usual going rate.

Thanks
Cam
