The Tier 1 Prospector Farm is found in the Shire. Try creating an alternate Hobbit character and make him an Explorer for his Crafting. This farm has both Prospector materials and Forester materials. Go to the town of Micheal Delving in The Shire, then display the world map so it shows the town name Micheal Delving. Find where the "G" in Micheal Delving is. Go to that general area and you will certainly find at least two or three Prospector Nodes (Tin Deposits and Copper Deposits). Make sure to have your Prospecting Tracker on. There is a mound that you can stand on that can reveal any of the three nodes that appear. By doing this, you can almost instantly run to it and grab the node. An Explorer is also acceptable for this, not only for its Prospecting ability but also the Forester. Sometimes Rowan Branches will appear at the bottom of the hill to the right of the building, and at the top near the few trees.
For easy cash, kill Wights and Barghests in the Barrow-Downs. The Barrow-Downs are found southwest of the town of Bree. If you leave when all five of your bags are full, you should make about 150 to 300 silver coins.
