Currency
Currency items are weightless tokens of exchange that define the value of all the other items. When trading with NPCs, the price of every item placed in the barter window is expressed in currency units, and any purchase above 50,000 units requires pure currency to execute.
In FOnline 3, no single universal currency exists. Instead, the money accepted in a given location depends on the faction currently in control. Each of the five lore factions mints its own currency, which is the only legal tender in locations under that faction's control.
Most major locations offer a unique type of service that can only be purchased with the ruling faction's currency. Players who seek these services must thus spend that faction's currency, reducing the amount that remains in circulation.
Caps remain in the game as a faction‑independent key currency. They are accepted only in the few remaining neutral locations and are therefore not very valuable for purchasing goods. Their main usefulness is in providing a stable baseline for tracking the relative value of the five faction currencies.
At any given time, the five lore faction currencies are worth 9, 13, 17, 21, and 25 caps respectively, with higher values assigned to currencies that players hold in smaller total quantities: the least‑held currency is worth 25 caps, and the most‑held is worth 9 caps, with the others falling in between.
Currencies
FOnline 3 has six main currencies: five for locations controlled by one of the five lore factions and one for locations that are neutral, see the table below.
Las Vegas (40:32) uses its own currency, 
Golden Dollars, bringing the total number of currencies up to seven.
You may occasionally encounter currency-like items, such as 
Pre War Money or 
Kokoweef Mine Scrip, but those are purely collectible items.
GM Auctions occasionally allow players to use Brahmin Dung as currency so think twice before you throw it away.

Currency exchanges
There are six locations that provide the (limited) ability to exchange currencies: NCR (34:27), Broken Hills (29:17), The Hub (31:40), San Francisco (9:25), New Vault City (16:8), and Redding (14:11).
To perform a currency exchange, (1) initiate barter with a banker NPC; (2) drag the currency you wish to acquire from the banker's inventory into the banker's offer area; (3) drag enough currency from your own inventory into your offer area to match or exceed the value of the banker's offer; (4) click the "OFFER" button to complete the exchange. Note that all values will be displayed in caps regardless of the currency the location normally uses.
