Bottle cap (Fallout 76)

Bottlecaps [sic] are miscellaneous items that can be found throughout Appalachia, and are almost exclusively used by wastelanders as currency throughout the post-War United States, though also accepted by vending machines throughout the region, as well as The Whitespring due to the celebration of Nuka-Cola Quantum's release.

Unlike other games in the series, there is a hard capped limit to caps. The total maximum amount of caps is 25000 caps per player character.

Characteristics
As well as being useful for currency, bottlecaps can also be used as shrapnel within bottlecap mines, and can cause severe damage. While many wastelanders inevitably destroy many bottlecaps creating these mines, bottlecaps always manage to remain at consistent numbers throughout the wastes, thanks in part to a few counterfeiting organizations, as well as there still being Nuka-Cola bottles to obtain caps from.

Locations

 * Bottlecaps can be found randomly in most containers, as well as upon most enemies, namely Scorched and feral ghouls.
 * Caps stashes can be randomly found around Appalachia awarding a sizable sum.
