Items Worth Alot Of Money, From quests?

Depending on your definition of 'a lot', the -50health Grim Cesta from one of the quests in Old Ascalon is good. They usually go for about 5k, though I wouldn't think demand is as high now as it used to be. I went after that weapon casually and it took me 7 hours of solid gameplay. Now I'm sure you can speed that time up considerably but even then it's not going to be worth the 5k-10k.

The best 'quest' I think of to farm would be FoW. Everyone does it for a reason.

What does it matter how long it takes? No one said anything about farming it. It's just a quest that rewards something that you can get some cash for, like the OP asked. For a new player (who would consider 5k a lot of money) playing through Prophecies properly doing this quest is a nice monetary boost. Just because the value pales in comparison with more advanced money making techniques doesn't mean it should just be ignored.

PS: As I mentioned earlier, I wouldn't have thought it would be easy to find a buyer nowadays, but I saw someone wanting one in LA a couple of days ago (I've only started playing again in the last week or two, so I don't know if that's a good representation of the wider community (probably not) but nonetheless there seem to be people out there that want them).
