If you're going to ICC, no it's not worth it.
If you're talking about an alt, in my case it would be worth it. I'm not going to run ICC often enough on my alts to make it likely that I'd get something there reliably. If I got a drop on one of my toons, I might consider selling it... but honestly, the only things I care about that can be purchased with gold is a handful of interesting mounts.
