Unlimited gold:
When you get the Chief Fisherman's' Daughter, go to the
beach where she goes to find the Aquamarine. When you
fight the little Jewel Leapers. they give you the stones
that are needed to make Runes. Get a large number of them
and some gold, then go to the Rune-Makers shop. You will
want to Refine those Gems into Runes, which cost 230 gold.
When they are refined, the Rune Shop will buy them back at
400 to 500 gold.
