Golden dragonscale chest

[Killarius]

So I have been contemplating weather it's better to sell the gold chests or to open them. But a missing ingredient in my decision is what do the chests have in them at best and the rates? I've opened 2 and have gotten nothing. They are only worth 6k. But I would like the know what possible loot I could obtain by opening them. If anyone is willing to share some insight I'd much appreciate it. (:

I think only good loot is wurmtongue egg.

They also have Champion gear (oddly). I open them because I'm too lazy to list them, but I usually sell the golds. Not to mention I rarely have regular chests (most mine are elite).
