Age of Empires EditGold Mines in Age of Empires are rare and the gold extracted from them is often crucial for victory. Mining gold is a quicker and often safer method of acquiring gold than trading. Gold Mines sometimes appear in groups and sometimes singly. If Coinage is researched, the productivity of a Gold Mine increases from 400 to 500.
Age of Empires II EditGold Mines in Age of Empires II are more common than in the first game, and gold is more regularly used as a resource. As such, its value is reduced, although it is still quicker and more efficient to gather from a Gold Mine than trade with other players or through Relics.
Age of Mythology EditGold Mines in Age of Mythology are quite common and nearly all military units require gold to be produced. Any worker unit can mine gold from a gold mine, although Dwarves are the game's most efficient miners.
Age of Empires III EditAge of Empires III does not have gold as a resource, but instead has coin, an amalgam of all forms of wealth. In addition to Gold Mines, players can obtain coin from Silver Mines, Copper Mines, and Tin Mines (The Warchiefs). All of these are used up rather quickly.
"In 1848, the discovery of gold at Sutter's Mill in what would soon be California kicked off a gold rush that brought tens of thousands of hopeful prospectors across the wild frontiers of America. The influx of prospectors, whether they struck it rich or not, caused a boom in the economy focused on serving the needs of these prospectors. This further supported and reinforced the drive west with railroads and settlements. Sutter himself was a farmer who discovered a gold nugget in a river running through his land. He was ultimately ruined when his farmhands ran off to join the search for gold and his livestock were poached by squatters."
