Gold (ゴールド gold), abbreviated as Ｇ, is the currency used in every Fire Emblem series game except Gaiden, where shops and money do not feature. In all of its appearances gold is accumulated and used by the player to fund their army, and can be used to purchase items and weapons from shops and armories, or occasionally to hire new units.
In most Fire Emblem games
The majority of installments in the serie handle gold through giving the player's army a communal supply thereof. Under the player's direction, any unit can use the army's gold to purchase items from shops located, depending on the individual game, on the chapter maps, the world map, the preparations screen or at the base.
Most of the time, the player will start the game with a set amount of gold. Further gold is obtained through selling items, finding it in treasure chests, winning arena battles, receiving it from villages or in cutscene events. The majority of games have a small number of special and rare items which serve no use beyond being sold to shops in exchange for high amounts of gold, such as the Red Gem or Bullion.
Genealogy of the Holy War features a significantly different system of handling gold than the rest of the series. In this game, instead of the communal gold supply, every unit has their own personal supply of gold. Units can use gold to buy or repair weapons from the shops located in castles, or can use it to be healed at the churches on the map for a sum of 5G per hit point restored; in Chapter 2, Beowolf can be recruited by any unit by paying him a sum of 10,000G, which he keeps upon joining you. The maximum amount of gold any one unit can carry at a time is 50,000G.
The primary means of receiving gold is through villages: every village in the game will give visiting units a sum of gold, sometimes in addition to an item. An undamaged village rewards the unit with 5,000G, and the amount decreases by 500G per turn of damage sustained by the village from Brigands until the village is destroyed. As with in other games, units can also receive gold by selling items or winning rounds of combat at arenas. Additionally, Thieves, Thief Fighters or units wielding the Thief Sword are equipped with the Steal skill, which automatically steals all of an enemy unit's gold upon damaging the enemy and adds it to the unit's own stockpile.
There are only two ways of directly transferring gold between units: a Thief (Dew, Patty, Daisy) can give all of their gold to another unit, and two lover characters can give each other all of their gold. In either case, the giving unit always gives up all of their gold to the receiver, unless this would result in the receiver having an amount of gold above the 50,000G cap: in this case, the giving unit will only give the receiver enough gold to reach the 50,000G cap and will keep the remainder.
Additionally, all classes are assigned a base amount of gold which they possess by default. While this is not particularly relevant to playable units, this results in almost all enemy units having a supply of gold, which can be stolen through the Steal skill.
