Yeah these are so nice-for the right buyer. That's the problem with gold wands/staffs and anks/artifacts/idols-SOOOO hard to find the right buyer. Also you are fighting the collectors anks/idols/artifacts with these rare ankhs. Why use this when you can get a +12 energy 20%recharge/20%cast speed collectors offhand for almost every magic using class/attribute type.
I'd say salvage it or sell to merchant. Otherwise maybe 1k.
I salvage like 2-3 golds like this a day. So don't feel too bad.
Good rule of thumb: If it doesn't add mana or hp you can almost guarantee that the collectors items are better and nobody would want it.
