Eternal Orb, keep it in HC or move it?

So I have an Eternal Orb from long ago in my Harcore stash and I was wondering where it is more valuable? I play mostly only standard and temporary leagues so I would be moving most of the currency to Standard anyway. I believe in standard it is worth 17 exalted at the moment, could I be getting more for it in Harcore or are the rates of Harcore:Standard not good and should I just sell it on Standard?
