From: Bangladeszanin A good place for gold farming would be the Isle of Neos, during the day - one Gold Golem is worth around 700 gold.
they also appear in groups sometimes, they're rather common and since you will probably have to grind soon after argonia you may want to spend a while there before moving to some place with metal slimes.

Gold Golems seem to move around on the map. If you try to farm one spot, you'll get a ton of them and rake up cash fast, then suddenly they'll dry up and it'll be several "days" (in-game time) before they start showing up to that same spot in decent numbers again.
