Treasure Hunting in Jade Forest
This method is very simple, and does not even require a flying mount, although it helps. However, you must be level 85+. Every Pandaria zone is covered in treasures. There's greys, gems and gold coins. There's also more valuable items that you can equip or keep in your bags. The gold is coming from the greys, treasures and gems. Most players haven't even noticed these, so they're always there waiting for you.
Here's the treasures you can find while in Jade Forest.
1. Pandaren Ritual Stone
Location: 23,35
Vendor price: 105 gold
2. Ancient Pandaren Tea Pot

Location: 26,32
Vendor price: 100 gold
3. Lucky Pandaren Coin

Location: 31,27
Vendor price: 95 gold
4. No gold gained here
5. No gold gained here
6. No gold gained here
7. Gem cache in a cave
Location: 62,27
Contains: Gold coins and Gems
Monsters are level 90 here and flying mount helps getting here, and out of here.
8. Offering for the Dead

Location: 46,80
Contains: Gold coins
If you think you can find a better use for these gold coins and choose to loot them, a curse falls upon you! Thankfully, it's not too serious, as all that happens is just your mounts turning white/colorless for a while. Extra cool looking!
9. Sunken Treasure

Location: 51,100
Contains: Gold coins
What are the rest of the numbers on the map?
There's many more treasures awaiting you in each of the World of Warcraft Mists of Pandaria zones. However, they will not make you any gold, so I will be talking more about them when Loot Hunter gets a new, shiny site and is made free to use. There will be lots more than treasures then, too!
