The Elder Scrolls Online's gold is earned through player vs environment instead of points like in player vs player interaction. It is specifically found on vanquished enemies that players have slain in Tamriel, lying on the ground through out the online world, or by completing quests in game. Players do have other ways to obtain the currency including selling items from their inventory or from trade and skill related tasks or items. No matter how the players earn their gold or where in Tamriel they are, everyone will need just the one kind of currency to make all of their purchases. But how can this be with the three fighting alliances and players' in game purchases?
Unlike what usually happens in the real-world, Daggerfall, Ebonheart, and Aldmeri are all "happy" to use the same eso gold pieces as a common currency. This acceptance is nice because then there is no need for banks or exchange rate stores between the three areas of Tamriel. However, gold is the only denomination in Elder Scrolls Online. This could make the purchase of smaller items awkward if there were smaller items. As it turns out, players of ESO will not worry about buying small items as purchasing and selling will be centered around valuable weaponry and armory in addition to raw materials. No silver or smaller coins needed.
