I would suggest, as long as you are careful, wandering around the Lone-lands. There are
 * Rhudaur Castles = Good Loot
 * Ruined Dunedain towers = Very good Loot
 * Bandits - Bring a ranged weapon, and keep your eyes peeled, and they are a VERY good source of cash - they can drop up to 64 coins at once!

So, that is my suggestion. To be honest, I don't think I have ever crafted coins. Completing Mini Quests is also a really good way, especially if you use the Completed section of your Red Book and keep track of what kinds of quests give you lots of moolah!
