You could probably get a few k for this. Maybe 2-5 if you're very lucky. Others might disagree, but if you placed say a -5:18% and a +28 on here, you've got a perfectly functional very cool looking shield.
there are plenty of players out there who don't mind non-max/non-gold items as long as they're not losing out too much. I'd try to sell this or keep for a hero.
