Gold Mine

Gold mines are found in Age of Empires, Age of Empires II, Age of Empires III and Age of Mythology.

Age of Empires
Gold Mines in Age of Empires are rare and the gold extracted from them important. It is a quicker way of acquiring gold than trading (and often less dangerous). Gold mines sometimes appear in groups and sometimes singularly.

Age of Empires II
Gold mines in Age of Empires II are more common than the original version and gold is a more commonly used commodity. As such the value of gold is reduced although it is still quicker and more efficient to gather from a gold mine than trade with other nations.

Age of Empires III
Age of Empires III doesn't make us of gold, rather coin is used. This can be acquired from either a gold mine, a silver mine, a copper mine(The Warchiefs) or a tin mine(The Warchiefs). All of these are used at a fast rate and typically do not last.

Age of Mythology
Gold mines in Age of Mythology are quite common and many units require gold to be produced. Any villager unit can mine gold from a gold mine, although a Dwarf is the most efficient miner in the game.
