Bottle Cap (Fallout)

Bottle caps are the standard currency in Fallout.

Characteristics
The Nuka-Cola bottle caps are backed by the Hub merchants in the Core Region. The reasoning for their support is that the technology to manufacture bottle caps and paint the surface has been lost in the Great War, which would greatly limit any counterfeiting efforts. Secondly, there is a limited number of bottle caps, which would serve to preserve their value to some degree.

Bottle caps are also called Hubbucks, because they originated from the Hub.
