The mines, I think level 80+ if I'm not mistaken have gold ore nodes. You take 5 gold ore with 1 coal and toss it into a furnace, which you have to craft. A few in game hours later and you'll have a gold bar. Same principle applies to Cooper, iron, quart, etc
Someone please tell me how to get gold? Itís like 400G at the blacksmith. I spend until 10AM watering and barely have time to get my energy back up before 2PM after selling crops for the day.
For energy, try foraging and crafting field snacks. I think field snacks are just 1 each of Acorn, maple seed, and pinecone. You should be able to make dozens of them if you clear some forest area. They fall of trees you cut down.
