If you want to farm for gold, then I suggest you create a rune book with several places where mobs drop the good gold. That way you can jump from place to place in case a spot is being camped or you grow bored with a place. When I farm gold, this my typical routine:
1. Start with the Sphynx, Up to 2 of them. No rune but world tele to Ilshenar/Rock Dungeon, head to desert. Drop 7 - 11k each.
2. Balrons, 2 in Hythloth, 5 in Tera Keep all markable. Then world tele for Blood Dungeon & Montor & others. 3 to 5k
3. Lurgs, In Tammel and Fel. Mark the Tram spot. Between 3.5 and 4.5k
4. Yamadons, 2 places in Tokuno, both markable. Around 2.5k
5. Depending on your skill, pets and tactics then another place is the Vampire area outside Umbra. Almost everything in their is great for weapon experience points and fame gains. Markable
Vampires - 600gp; Black Liches (2 -3) 5k; Onxy Dragon - 7k(?); Sapphire Dragon; Shadow Wyrms; and Black Lich Lord which drops and acts like Dark Father in Doom Gauntlet. Other critters in there as well.
For lesser skilled hunters, I would suggest the last two bosses in the Citadel. About 1.5k each and fast respawn time. You can recall to the entrance, then foot it to their location inside.
I've never had a problem finding most of these places open as I recall to them. Good luck and happy hunting.
