Gil is the most widely accepted form of in-game currency. The amount of gil you hold is indicated on the currency panel. Gil can be exchanged between players via direct trade, by purchasing or selling items on the Market Board, or by sending letters through the Delivery Moogle. Players can earn gil by completing quests, guildleves, dungeons, duty roulettes, and Challenge Log entries, as well as by killing monsters in dungeons, and selling items. The Gil cap is 999,999,999 for the player and each retainer, while players on a Free Trial are capped at 300,000.
When the Sixth Umbral Calamity came, laying waste to the land and swallowing up once-proud nations of magi and wise men, the currencies minted and circulated by these civilizations lost their value, and the economy of Eorzea returned to a primitive system of barter and trade. As the realm recovered and rebuilt itself after the dawn of the Sixth Astral Era, the currencies of Mhach and Amdapor came back into limited use, their values assigned roughly according to the worth of their component metals.
As city-states and nations came to flourish, certain interests took steps to mint their own currencies, with Sharlayan and Ishgard quick to follow suit. As contact between nations in these times was limited at best, no effort was made to introduce a universal standard, and for years, many myriad currencies were exchanged throughout the land. This changed in the years of peace that followed the Autumn War. Trade and diplomatic relations between nations flourished, and for reasons of economic convenience, the demand for a universal currency became stronger.
In the year 1477 of the Sixth Astral Era, the leaders of Eorzea's six great city-states came together and reached the decision to mint a universal currency to be used the realm over. So it came to be that gil, a coinage once used by the ancient Allagan empire, was reinstituted as the standard currency for all the land.
In times of eld, coins would typically bear designs inspired by heroes, leaders, or religious imagery of the nations that minted them. With the introduction of gil as a universal currency, a consensus of experts from all nations made the decision to adopt neutral designs—ones not rooted in the traditions of any one culture or nation—in the interest of avoiding needless debate. To this end, the face of Nymeia the Spinner was chosen to grace the one-hundred gil coin.
An exception to the rule can be found in the commemorative one-gil coins issued by the grand companies for Foundation Day, which are emblazoned with the images of the leaders of the respective city-states.
