Gil is the main currency of the FFd20 system and is seen throughout the Final Fantasy franchise, from oval coins to circle coins, silver to green. Depending on the world or games you’ve played you’ll have seen various styles of gil but a standardised format is created for use in FFd20. Feel free to change colors or shapes to fit the worlds your campaigns are set in.
Gros (pronounced Grós) is another type of coin which denotes a decimal system akin to how cents operate to US dollars. Ten gros (0.10 gil) is equivalent to one silver in Pathfinder, and one gros (0.01 gil) is equivalent to one copper in Pathfinder. One hundred gros is equivalent to one gil (1 gold in Pathfinder is 1 gil in FFd20).
No matter the type of coin, all gil and gros variants weigh the same amount of 0.02lbs or 1/3 of an ounce, or 50 coins to the pound.
Each coin has a diameter of 27 mm (2.7 cm) and a thickness of 2 mm (0.2 cm).
Coins are made of a metallic alloy that is then painted and minted into different variants, a special mixture makes the coins that are holed (typically gros) to weigh the same amount as non-holed coins.
There are no forms of paper money in normal play, though games may use paper money as they so wish or to better emulate the game Final Fantasy Tactics A2: Grimoire of the Rift for the Jylland region of Ivalice.
Banks are common in most worlds, though without electricity or computers gil cards are not widely used. For games that emulate Final Fantasy VIII you may use banks and gil cards to work out your players’ money, in which case payments are made straight into bank accounts and transactions can be made with swiping their gil cards into readers.
Denominations of Gil
The copper variant of Gros is the most common denomination of coins for the lowest class of civilians. Used for buying day-to-day items such as food, water, and low-end clothes, these coins are often bent, dented, or lost their lustrous color over the years. This variant is written as 0.01, counting as 1 hundredth of a gil.
The silver variant of Gros is technically an alloy of tin and pyrite, colored silver in the minting process. Used for bulk purchases by the lowest class of civilians or for buying up singular goods of higher value such as furniture and tradesmen tools. While considered silver by the masses, this coin does not effect those with weakness to silver in any fashion besides a momentary fear. This variant is written as 0.10, counting as 1 tenth of a gil.
 The first denomination of gil, and the most prevalent in lower-class society, is the 1-gil coin, also known as singles. Colored bronze, this coin is often seen as dingy, or even covered in dirt and soot as the “workman’s” gil. |

 The second denomination of gil, and seen frequent use in lower-class to middle-class society as well as traders, is the 10-gil coin, also known as silvies. Colored silver, this coin is more than not covered in fingerprints and marks. |

 The fourth and final denomination of gil, seen used only by the richest of people, adventurers, and the army, is the 1,000-gil coin, also known as cactuar gil. Colored green, this coin is almost always sparkling. |
