Post-War currency

The currency in the Fallout world has varied from game to game. In Fallout 1 bottlecaps were used as currency, and in Fallout 2 it was dollars. In Tactics, you used a mixture of Brotherhood scripts and Ring pulls. For Brotherhood of Steel, well, no one really cares, do they? (its Caps, though for some ungodly reason, BAWLS bottle caps are worth extra)
