To give you a feel for things:
  • I did 68-80 on my shams all questing. Hit 80 in Storm Peaks. Ended up with 1900g from the last half of Storm Peaks and all the Icecrown quests.
  • I did 70-80 in NR on my druids. Did a few (as in, no more than 3 runs each) more dungeons. Hit 80 in New Ungoro. Ended up with epic flight + another ~3000 gold each from Storm Peaks/Icecrown quest lines.
  • I did 70-80 on my hunter in NR, all quests. Ran him through DF enough to complete instance quests and went back to questing. All rested xp. Hit 80 in Zul'drak. He ended up with 8k gold from the last 4 zones of quests plus all the dailies he was able to do for the two casual weeks I took leveling him.


Thinking about it a bit, I suspect you could make something like 15k gold from doing all the NR quests at 80. I also suspect that's a conservative estimate. :P
