NCR dollar

In Fallout 2, money backed by gold is being used as the standard currency by the 3 big powers: New California Republic, Vault City and New Reno. Bottle caps have become worthless.

The NCR still uses their dollars in the area around New Vegas, but bottle caps have come back into use. The money is no longer backed by gold, after the Brotherhood of Steel destroyed NCR's gold reserves, so the money is backed by water instead.
