關於an overview of currency in the Fallout series of games，參見Currency。
Bottlecaps are miscellaneous items in Fallout 4, which are widely used as currency throughout the post-War United States. Bottlecaps can come from certain drinks, such as Nuka-Cola, beer and other malt beverages.
Bottlecaps are used as currency in the Commonwealth.
Bottlecaps can be found pretty much anywhere in the Commonwealth, in varying amounts.
- Nuka-Cola caps seen throughout the game either in advertisements, memorabilia or as actual collectible caps such as those thrown out by the bottlecap mine have the classic Nuka-Cola logo on them, but this logo is missing on the cap of the bottled Nuka-Cola item, which is simply plain red.
- Bottlecaps are not needed to craft bottlecap mines in Fallout 4. However, bottle caps can be collected from detonated bottlecap mines.
- With the Fortune Finder perk, there will be a better chance of finding bottlecaps. If this perk is at max rank, there is a chance that enemies explode into a shower of caps upon getting killed.
- Unlike in previous games, bottlecaps cannot be stored or dropped in Fallout 4.
