A short distance northeast of Rockery Haven are smugglers which drop fake documentation. Each documentation is worth 91G, and they drop it almost every time. 99 of these are worth 9k. This requires about five minutes with a second class character (above level 40). It is a very easy and fast way to get money. Note: Voyager is recommended for best results.

Use the following trick if you are at least level fourteen and need some money but cannot fight strong monsters. Go to Argent. Go to the mines directly west of the battlegrounds entrance (you may have to go up a bit). There will be level 12 bear cubs that drop paws and fur that are worth twenty to thirty gold each.

Go to the Zephyr Isle and fight the green wolf to get the Sealed Blueprint (worth 750,000 gold). When you are at levels thirty to fourty, go to Rock Haven. Kill a Smuggler mob. They usually drop fake documents worth 91 gold each. If you get ten stacks of documents you can got 99,000 gold.
