A simple mod that adds bottle caps as currency.
This is not programmed into the loot tables of any mobs or chests so you will need to create your own modpack to add them, or use loot-changing mods.
Combaining 9 bottle caps 
gives you a cap stack 
Combining 9 cap stacks gives you a bag 
Melting one cap in a furnace gives you one iron nugget
Only avaliable in Forge 1.20.1, made in MCreator
(This is my first mod I don't know what I'm doing lol)
