Pre-War money (Fallout 3)

Pre-War money is the currency of the former United States. Although faded, the notes appear to be American dollars. Pre-War money is no longer the official currency of the United States. The actual currency varies from region to region. The West Coast has developed a new currency after having used bottle caps for a number of years. The DC region, however, still uses these caps, having no means to produce its own currency.

In Fallout 3 and Fallout: New Vegas, pre-War money appears as a stack of indistinguishable bills. The item is valued at 10 caps per stack and is affected by the player's Barter skill. Pre-War money is somewhat plentiful. It can be found nearly anywhere money might be found in real life such as cash registers, safes, and desks. As it has lost almost all value to the inhabitants of the Wasteland, it can also be found in garbage cans.

Uses
Pre-War money doesn't have many uses in either game. Its weightlessness and relatively high value makes it an ideal item to sell to merchants. It can be used as ammunition for the Rock-It launcher in Fallout 3, though as it is more useful as a traded item it isn't the best choice of ammo over other miscellaneous items. Or you could just collect them and make a large pile of money in your place of residence in either game.

Locations
Pre-War money is located throughout the Capital Wasteland, The Pitt, Point Lookout, Adams Air Force Base, and the Mojave Wasteland.
