For coin farming using Adventurer Cookie, it'll become more efficient in Primeval Jungle provided you use the right treasures. Also, Ghost Pirate's Island of Coins has been heavily buffed, with many more Gold coins and a slower energy drain.

For Mystery Box Farming, just run in Episode 2 (fast running cookies guarantees 2) or Special Episode 1 (almost always guarantees 3).
