PTCGO: Which Booster Box has the most value?

So I have a huge store-credit at my local card shop and I have the option to buy a booster box. The problem is I don't know which box to get. I'm content with the deck that I have and honestly, I would not mind turning my booster box purchase into some cash. With that said, which one of these boxes would rack me up the most cash?

From Primal Clash all the way to Guardian's rising. The only one they don't have is Generations.

Thank you in advanced!

GRI and ROS have the big money cards of the format, so those are probably your best bet. Plus, they were both generally good sets.
