This quest:
http://everquest.allakhazam.com/db/quest.html?quest=224 gave very good experience during classic and at least through Kunark. I cannot give you precise numbers, but I once levelled a druid to 29 on nothing but this and bone chips in Kaladim and this quest was actually better experience (for one Polar Bear Pelt) than Kaladim for 4 bone chips.
I did it today at level 2 and my exp bar barely budged - at most a blue of experience for 3 turnins. If you read some of the comments on the alla's thread, one person references getting 4 yellows of exp at level 3 for 3 turn-ins. That is more in line with what I remember.
Again, I have no way to give precise numbers, but it was better than Kaladim bone chips - I just don't remember how much better.
