Pre-War money (Fallout: New Vegas)

Pre-War money or United States Dollars are stacks of banknotes of various denominations, appearing in Fallout 3, Fallout: New Vegas, and Fallout 4.

Characteristics
In Fallout: New Vegas, pre-War money appears as a stack of indistinguishable bills, held together by a green seal. 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, suitcases and desks. As it has lost almost all value to the inhabitants of the Wasteland, it can also be found in garbage cans.

Uses
The primary usefulness of pre-War money is as a trade item, owing to its weightlessness and relatively high value.

In the first add-on for Fallout: New Vegas, Dead Money, pre-War money can be exchanged for (or from) Sierra Madre chips while inside the Sierra Madre Casino. The exchange rate is 1:1 — one chip for one (stack of) pre-War money — making it a potentially profitable source of income given the availability of the Sierra Madre chips.

Locations
Pre-War money is found throughout the Mojave Wasteland, Sierra Madre, and Zion National Park. Within the Mojave Wasteland, there are a lot in Searchlight Airport, the REPCONN headquarters, suitcases in Black Mountain and the bank within the Atomic Wrangler.
